Module 18: Diplomacy

International organizations, treaties, and soft power

Part A · what diplomacy is and why it exists
The core purpose: managing relations between states without war
Diplomacy is the art of letting someone else have your way. — Daniele Vare, Italian diplomat
Why diplomacy exists
States have conflicts of interest. War is catastrophically expensive. Diplomacy provides a way to manage these conflicts through communication, negotiation, and agreement rather than violence.
What diplomats actually do
Represent their state's interests in foreign countries. Report on developments. Negotiate treaties and agreements. Protect their citizens abroad. Communicate official positions — and unofficial signals.
The Vienna Conventions
1961 (diplomatic relations) and 1963 (consular relations) set the global rules. Virtually every country in the world is a party. These treaties created the framework that all modern diplomacy operates within.
Part B · the UN system — architecture and members
United Nations (UN) 193 member states founded 1945

Purpose

Maintain international peace and security, develop friendly relations among nations, promote human rights and international law.

Headquarters

New York (main), Geneva (human rights, humanitarian), Vienna (nuclear, drugs, crime), Nairobi (environment).

Budget

~$3.5B/year (regular budget). Assessed contributions — USA pays ~22%, China ~15%, Japan ~8%, Germany ~6%.

The UN was founded after WWII by the victorious Allies to prevent another world war. Its founding document, the UN Charter, is effectively the closest thing the world has to a constitution for international order. 193 of the world's 195 recognised states are members. Non-members: Vatican City (observer), Palestine (observer), Kosovo (disputed).

General Assembly (UNGA)

193 members — 1 country, 1 vote

All UN members meet here. Passes resolutions by majority vote. Resolutions are non-binding — they represent world opinion but cannot legally compel states. The great forum of the world. Each September heads of state make addresses (the "General Debate").

Security Council (UNSC)

15 members — 5 permanent + 10 rotating

The only UN body that can pass binding resolutions — including authorising the use of force, peacekeeping missions, and economic sanctions. The 5 permanent members (P5) each hold a veto. This is where real power sits. See Part C.

International Court of Justice (ICJ)

15 judges, The Hague

Settles legal disputes between states (not individuals). Cases: border disputes, treaty interpretation, state responsibility. Judgments are technically binding but enforcement depends on the Security Council — meaning a P5 member can block enforcement of a judgment against itself.

International Criminal Court (ICC)

124 member states, The Hague

Tries individuals (not states) for war crimes, crimes against humanity, and genocide. Separate from the UN (though related). The USA, Russia, China, India, and Israel have not ratified the Rome Statute — their nationals are largely beyond ICC jurisdiction. Has issued arrest warrants for Putin (2023).

Secretariat / Secretary-General

~44,000 staff worldwide

The UN's administrative body. The Secretary-General (SG) is the world's chief diplomat — António Guterres (Portugal) since 2017. The SG can use "good offices" to mediate conflicts but has no independent power to compel states.

UN Specialised Agencies

15+ autonomous organisations

WHO (health), UNESCO (culture/education), FAO (food), UNICEF (children), UNHCR (refugees), ILO (labour), IMF (finance), World Bank (development), IAEA (nuclear). Each has its own membership, budget, and governance. Related to but separate from the UN proper.

Part C · the Security Council and the veto — the most powerful diplomatic mechanism
The P5 and their veto power
USA
P5 since 1945
Vetoed most on behalf of Israel (40+), also Cold War vetoes
Russia
Inherited USSR seat (1991)
Highest veto count (~120+). Routinely blocks action on conflicts where it has interests
China
P5 since 1945 (ROC→PRC 1971)
Used veto sparingly until recently; now more assertive, often with Russia
UK
P5 since 1945
32 vetoes, mostly Cold War era. Has used veto jointly with USA and France.
France
P5 since 1945
18 vetoes; largely Cold War and colonial. Pledged not to veto on genocide/mass atrocity cases.
How the veto works
A resolution needs 9 votes to pass. But if ANY of the 5 permanent members votes "no," the resolution fails regardless of how many others voted yes. Even 14-1 is a failure if the 1 is a P5 member. An abstention is NOT a veto — it allows the resolution to pass if enough others vote yes.
Why it exists and why it's controversial
The veto was the price of P5 participation in 1945 — the great powers would only join if they couldn't be outvoted. Without it, the UN wouldn't exist. Critics: it allows the P5 to protect themselves and their allies from accountability. Reformers want to expand or limit the veto, but any reform requires P5 agreement — which they'll never give.
Recent examples: Russia vetoed every UNSC resolution on Syria (2011–2023), blocking any authorised intervention despite 500,000+ deaths. Russia vetoed resolutions condemning its 2022 invasion of Ukraine. The USA regularly vetoes resolutions critical of Israel. China and Russia have jointly vetoed resolutions on Myanmar and Venezuela. The veto means that wars involving P5 members or their close allies are almost always immune from UNSC action.
Part D · major international groupings — click to explore
Part E · special diplomatic formats — why odd groupings exist

5+1 (P5+1 / E3+3)

Iran nuclear negotiations

The 5 UN Security Council permanent members (USA, Russia, China, UK, France) plus Germany (the +1). Germany was included because of its economic weight and EU role — not because it's a nuclear power. This format produced the JCPOA (Iran nuclear deal) in 2015, from which the USA withdrew in 2018 under Trump. Talks resumed under Biden but remained unresolved. The format illustrates how ad hoc groupings form around specific issues when the UN framework is too unwieldy.

Normandy Format

France, Germany, Russia, Ukraine

Created in 2014 after Russia annexed Crimea, meeting in Normandy on the D-Day anniversary. France and Germany mediated between Russia and Ukraine. Produced the Minsk Agreements (I and II). The format collapsed effectively with Russia's full-scale invasion of February 2022. Illustrates how bilateral conflicts often require third-party mediators to create a table that both sides will sit at.

Six-Party Talks

North Korea's nuclear programme

USA, North Korea, South Korea, China, Japan, Russia — six parties to negotiate denuclearisation of the Korean Peninsula. Began 2003, collapsed 2009 when North Korea withdrew. China is included as the key interlocutor with Pyongyang. North Korea has since developed a full nuclear arsenal. The talks illustrate the difficulty: North Korea sees nuclear weapons as regime survival, not a bargaining chip.

Quartet on the Middle East

UN, USA, EU, Russia

Established 2002 to coordinate international positions on Israeli-Palestinian peace process. Effectively inactive since ~2014. Its failure illustrates a common diplomatic pattern: multi-party formats that include actors with conflicting interests (USA protects Israel; Russia has different interests) often produce statements but no action.

Contact Group (various)

Ad hoc for specific crises

A Contact Group is any informal grouping of states with an interest in resolving a specific conflict. Examples: the Ukraine Contact Group (now Ramstein Group) — 50+ countries coordinating military support for Ukraine. Bosnia Contact Group (1990s). These form because the formal UN mechanism is blocked (usually by a veto) and states need another framework for coordination.

Minsk Process / Agreements

Ukraine conflict 2014–2022

Two ceasefire agreements (Minsk I: 2014, Minsk II: 2015) between Ukraine and Russian-backed separatists, brokered by France and Germany via the Normandy Format. Neither was fully implemented. Russia invaded Ukraine on a large scale in February 2022, rendering the agreements moot. The Minsk process is studied as a case of how agreements can fail when one party treats them as delay tactics rather than genuine settlement.

Part F · sanctions, immunity, and practical diplomacy

Sanctions

Economic coercion short of war

Restrictions on trade, finance, travel, or technology intended to change a state's behaviour. Types: comprehensive (all trade — North Korea, Iran), sectoral (specific industries — Russian energy, arms), targeted/smart (specific individuals — asset freezes, travel bans). Effectiveness is debated: Iran has been sanctioned for 40 years without abandoning its nuclear programme; South Africa's apartheid regime partly collapsed under sanctions. Sanctions hurt ordinary citizens more than leaders who have offshore wealth.

Diplomatic immunity

Diplomats cannot be arrested or prosecuted

Under the 1961 Vienna Convention, diplomats (and their families) are immune from criminal prosecution and civil suits in the host country. The rationale: if states could imprison each other's diplomats, communication would cease. Embassies are technically inviolable — the host government cannot enter without permission. Abuse: diplomats sometimes use immunity to avoid traffic fines (~$16M owed in New York alone) or escape more serious charges.

Persona non grata

Diplomatic expulsion

A host state can declare a diplomat "persona non grata" (unwanted person) without explanation, requiring them to leave. Used to expel suspected spies, punish hostile acts, or signal displeasure. After Russia's 2018 Novichok poisoning in the UK, 28 countries expelled 153 Russian diplomats — the largest collective expulsion in history. Russia reciprocated, expelling Western diplomats.

Breaking off diplomatic relations

The nuclear option of diplomacy

When a state closes its embassy and recalls its ambassador, it signals a near-complete breakdown. It doesn't mean war — communication can still occur through third-party embassies (a country asked to represent interests). USA and Cuba had no diplomatic relations 1961–2015 (54 years). USA and Iran since 1980. The break creates problems: no visa services, no consular protection for citizens, intelligence gaps.

Back-channel diplomacy

Secret, informal negotiations

Official negotiations often cannot proceed in public — domestic politics, face-saving, and inflexibility make open talks fail. Back channels are unofficial, deniable contacts that explore compromise before anything is made public. Oslo Accords (1993 Israel-PLO) began as back-channel talks in Norway. Nixon's opening to China (1972) was prepared by Henry Kissinger's secret trip to Beijing. Most major diplomatic breakthroughs began in back channels.

Soft power vs hard power

Attraction vs coercion

Hard power: military force or economic coercion. Soft power (Joseph Nye's concept): the ability to attract and co-opt rather than coerce — through culture, values, and institutions. The USA's soft power includes Hollywood, universities, the dollar, and the idea of the "American dream." China is investing heavily in soft power (Confucius Institutes, BRI infrastructure) while also wielding economic hard power. The most effective states use both (smart power).

Part G · diplomatic vocabulary
Part H · test yourself

1. Russia vetoes a UN Security Council resolution condemning its invasion of Ukraine. The resolution had 13 votes in favour. What happens next, and what options does the international community have?

The resolution fails — one P5 veto defeats it regardless of other votes. Options: (1) The General Assembly can be convened under "Uniting for Peace" procedure (used in 1950 for Korea), where it can pass non-binding resolutions by 2/3 majority — the GA passed several resolutions condemning Russia in 2022 with overwhelming majorities (141-5, 143-5), though non-binding. (2) States can impose unilateral sanctions outside the UN framework — the EU, USA, UK, and others did exactly this. (3) Arms supplies to Ukraine outside the UNSC — this happened through NATO and bilateral agreements. The veto means the UN cannot authorise peacekeeping or enforcement, but it cannot stop states from acting unilaterally or in coalition. The war in Ukraine illustrated both the limits of the UNSC (paralysed by the Russian veto) and what diplomacy outside the UN framework looks like.

2. What is the difference between an ambassador and a consul, and why do countries have both?

An ambassador represents their state to the host government — they conduct political diplomacy, attend to state-level relations, and are based in the capital city. A consul represents their state's interests to private citizens and businesses in a specific city — they issue visas, help citizens in distress, authenticate documents, and support trade. A country might have one ambassador in Berlin but consulates in Hamburg, Munich, and Frankfurt to serve the large German cities. Ambassadors are accredited to the head of state; consuls are not. Diplomatic immunity is stronger for ambassadors; consular immunity is more limited. In practice, embassies also handle some consular work, and distinctions blur — many embassies have a consular section.

3. Why does Germany have a permanent seat in the G7 but not the UN Security Council?

Because the two institutions were created at different times with different logic. The UN Security Council was designed in 1945 around the victorious Allied powers — the USA, USSR, UK, France, and China (Republic of China, replaced by PRC in 1971). Germany was a defeated enemy state; giving it a veto on global security would have been unthinkable. The G7 was created in 1975 around economic weight — the largest industrialised democracies at that time. By then West Germany was the world's third largest economy and naturally included. The frozen 1945 structure of the UNSC means Germany (the world's 4th largest economy, with 84M people) has no permanent representation, while France (similar size) has a permanent seat and veto. This is one of the main arguments for UNSC reform — but reform requires P5 consent, which would mean diluting their own power.

4. What does it mean practically when a country "imposes sanctions" on another country?

Sanctions are legal restrictions that prevent your own citizens and companies from doing business with the target. A country imposing sanctions on Russia, for example, prohibits its own banks from processing Russian payments, its companies from exporting certain goods to Russia, and specific Russian individuals from entering or holding assets in the sanctioning country. Secondary sanctions go further: threatening to punish third-country companies that do business with the sanctioned state (the USA uses these aggressively — a Chinese bank that processes Russian payments risks losing access to the US financial system). Sanctions don't require the target's agreement — they restrict your own side's behaviour. The effectiveness is debated: Iran and North Korea have been sanctioned for decades without abandoning nuclear programmes; the threat of sanctions has occasionally changed behaviour (South Africa, Libya in the 1990s).

5. Why do the Oslo Accords (the 1993 Israel-PLO agreement) illustrate both the power and limits of back-channel diplomacy?

The power: the Oslo process succeeded in producing an agreement precisely because it was secret. In public, Israeli and PLO leaders couldn't negotiate — domestic audiences on both sides would have punished any sign of compromise. The back channel in Norway allowed exploratory talks without commitment; neither side had to defend what was discussed. By the time talks were public, the framework was agreed. This enabled mutual recognition — Israel recognised the PLO as the representative of the Palestinian people; the PLO recognised Israel's right to exist — a breakthrough impossible in public. The limits: the agreements were incomplete — they deferred the hardest issues (Jerusalem, refugees, final borders) to "final status negotiations" that never succeeded. They also lacked domestic buy-in — Israeli PM Rabin was assassinated by a nationalist Israeli in 1995 partly because of the agreements; the peace process effectively ended. The lesson: back-channel diplomacy can produce agreements that public diplomacy cannot, but it cannot substitute for the political will to implement them.
