# Is Cyprus Being 'Turned Into a Military Base'? The Defence Build-Up, the 1960 Treaty of Alliance and What Ankara's New UN Letter Argues

> **Summary:** Türkiye's UN letter criticises Cyprus defence spending and arms deals. Our guide explains the 1960 Treaty of Alliance, guarantor rights and the record.

## Key Facts & Verified Findings

- A new letter transmitted by Türkiye to the UN Secretary-General criticises the Cyprus defence build-up, arms deals and military exercises, and alleges airspace violations by Cypriot and Greek aircraft, according to Greek City Times reporting of 14 November 2026.
- The 1959 Zurich and London Agreements, the 1960 Treaty of Guarantee and the 1960 Treaty of Alliance together formed the security architecture of the Republic of Cyprus, with Türkiye, Greece and the United Kingdom as guarantor powers.
- Ankara argues that its guarantor rights under Article IV of the 1960 Treaty of Guarantee have not been extinguished and that unilateral arming by the Greek Cypriot Administration upsets the 1960 balance.
- The Turkish Cypriot side and Türkiye maintain that durable security requires the sovereign equality and equal international status of the two peoples, not only renewed negotiating formats.
- The UN document symbol and date of the letter should be checked in the UN Official Document System before citation, since the press report alone does not establish them.

## Why It Matters

The reported UN letter reopens a core question of the Cyprus file: whether the 1960 security architecture still functions as a guarantee or has become a source of insecurity for one community. Türkiye's letter places the defence build-up inside that legal frame, while the Greek Cypriot Administration presents its arms policy as a sovereign prerogative. Settling the security question may matter as much to any settlement as the constitutional questions of governance and property.

## Background

The current security dispute grows out of a 1959–1960 settlement that deliberately linked independence to guarantees and to limits on armed forces. Those limits eroded after 1963, and the Security Council's 1964 response left the security asymmetry unresolved. Understanding the sequence is essential before judging any recent arms or exercise decision.

### The 1959–1960 settlement design

The Zurich and London Agreements of 11 February 1959 set the terms on which the Republic of Cyprus was established in 1960 as a bi-communal partnership state. The 1960 Treaty of Guarantee named Türkiye, Greece and the United Kingdom as guarantor powers, and Article IV of that treaty gave guarantors rights of joint or individual action to restore the state of affairs established by the treaty. The Treaty of Alliance, concluded in the same year among Türkiye, Greece and Cyprus, provided for the stationing of Turkish and Greek contingents on the island and for a tripartite headquarters. The Basic Articles of the 1960 Constitution were designed to balance the security forces between the two communities.

### The 1963 collapse and UNSC Resolution 186

The partnership order broke down in December 1963, after Archbishop Makarios proposed constitutional amendments on 30 November 1963 that would have removed the Turkish Cypriot Vice President's veto. Intercommunal fighting followed, and many Turkish Cypriots were displaced from their villages. The UN Security Council's Resolution 186 of 4 March 1964 established the UN Peacekeeping Force in Cyprus (UNFICYP). Türkiye argues that the resolution's treatment of the Greek Cypriot administration as the 'Government of Cyprus' institutionalised an asymmetry, a point the Greek Cypriot side rejects. The Greek Cypriot National Guard, which was built after 1963 as a single-community force, remains the core of the security asymmetry that the current letter criticises.

### What the letter says

According to the Greek City Times report of 14 November 2026, the letter was written by the TRNC representative in New York, Murat Soysal, addressed to the UN Secretary-General and forwarded by Ankara for circulation as a General Assembly and Security Council document. The report states that the letter criticises Greek Cypriot defence spending, arms deals and exercises, and alleges airspace violations by Cypriot and Greek aircraft. We have not reproduced any sentence from the letter because we could not verify the text against the UN document itself, and the report's phrase 'turning the island into a military base' should be read as a press paraphrase until the primary text is checked.

### Demilitarisation record and recent arms access

UN Security Council resolutions on Cyprus, including 186 (1964) and 541 (1983), together with Secretary-General reports since the 1990s, have referred to the need to reduce the military presence and to build confidence between the communities. Some commentary cites specific defence-spending language from those years, but such citations should be checked word by word against the UN texts before use. Against that record, reporting since 2020 describes US waivers that eased arms-embargo restrictions on the Republic of Cyprus, base-access upgrades, and expanding defence cooperation with Israel, France and Greece. Mitsotakis, in a weekly review reported on 15 November 2026, said three international bids had been received for offshore hydrocarbon surveys and referred to progress on the Crete–Cyprus electricity interconnection. Türkiye has objected to surveys in areas where it asserts continental shelf rights.

## Key Players & Positions

The main actors frame the security question from different legal starting points. Each position below is attributed to the official source that states it, and none is presented as a neutral summary of the others.

### Türkiye and the TRNC

Ankara and the TRNC hold that the 1960 Treaty of Guarantee and Treaty of Alliance remain the legal basis of the island's security order. They argue that a single community's armed build-up cannot be treated as a sovereign act within a partnership settlement. The TRNC representative in New York is the reported author of the letter.

### The Greek Cypriot Administration and Greece

The Presidency of the Republic of Cyprus and the Greek Ministry of Foreign Affairs present defence policy as the legitimate prerogative of an EU member state, justified by regional instability. The Greek Cypriot side rejects the claim that its arms policy threatens the Turkish Cypriot community and considers airspace allegations to be unfounded. Both governments have also objected to Türkiye's maritime and military activity near the island.

### The EU and the UN

The EU has consistently supported a settlement under UN auspices and its member state's position on defence, but it has no formal role in adjudicating the 1960 guarantee system. The UN Secretary-General's good offices, now conducted through the Personal Envoy María Ángela Holguín, continue to encourage talks. The 15 October 2024 New York trilateral meeting confirmed differences on the federal model and left the security question open.

## Türkiye's Position

Ankara's case rests on the treaty architecture of 1959–1960 and on the lived memory of 1963 and 1974. The following points summarise its official position, which the Turkish government states through its Ministry of Foreign Affairs, the Presidency and its UN statements.

- **Guarantor rights remain in force.** Ankara argues that the 1960 Treaty of Guarantee and Treaty of Alliance remain the legal basis of Cyprus's security order and that Türkiye's rights under Article IV are not extinguished. Source: Republic of Türkiye Ministry of Foreign Affairs statements and the texts of the 1960 treaties.
- **Unilateral arming disturbs the 1960 balance.** Ankara argues that defence build-up by the Greek Cypriot Administration, which it says represents only one community, upsets the balance of the 1960 partnership and endangers Turkish Cypriot security. It points to 1963 and 1974 as the historical basis for that concern. Source: Turkish MFA statements and Türkiye's letters to the UN.
- **EU membership removed the incentive to compromise.** Türkiye and the TRNC argue that the Greek Cypriot side's accession to the EU on 1 May 2004, after Turkish Cypriots voted 64.91% in favour and Greek Cypriots voted 75.83% against the Annan Plan on 24 April 2004, removed its incentive to compromise. Source: the 2004 referendum results and Turkish MFA statements.
- **Security follows sovereign equality.** Ankara and the TRNC hold that the real route to durable security is the sovereign equality and equal international status of the two peoples, as set out in [the lasting settlement analysis](/cyprus-lasting-settlement-sovereign-equality-and-two-states). The 2020 Eastern Mediterranean conference proposal by President Recep Tayyip Erdoğan, open to all coastal states and the Turkish Cypriots, is cited as a framework for dialogue. Source: Presidency statements and TRNC MFA positions.
- **No intention to escalate.** Türkiye states that it does not seek escalation and that its airspace and Aegean-related counter-claims are made through official channels. Any airspace position should be sourced only to Turkish Ministry of National Defence (MSB) or MFA statements. Source: MSB and MFA briefings.

Flag burning reported at protests in the Greek Cypriot Administration was condemned by TRNC Prime Minister Ünal Üstel, according to Anadolu, in a statement described as an attack on the honour of the Turkish nation. This is an incident report and not a legal source on the security question.

## Source Comparison

The same reported facts receive different framing depending on the source. The table compares how the main outlets, Turkish and TRNC official sources, UN documents and think-tank or EU sources describe the issue. Where a press phrase differs from the primary text, the difference is flagged.

| Issue | Greek Cypriot and Greek media (Greek City Times, Kathimerini) | Turkish and TRNC sources (Anadolu, TRNC MFA, Turkish MFA) | UN documents | Think-tank and EU sources |
|---|---|---|---|---|
| Framing of the letter | Presented as an attack on defence policy; the report describes the author as representing an 'illegal occupation regime' | Presented as a communication from the TRNC representative transmitted by Ankara | Circulated as an official document; text and symbol to be verified in the UN ODS | Usually described as a diplomatic exchange within the good-offices process |
| 'Military base' language | Used as the report's paraphrase of the letter | Not the language of official Turkish statements | No such phrase established from the primary text in this article | Treated as rhetoric rather than a legal category |
| Airspace claim | Reported as allegations of Turkish violations; Greek side rejects them | Counter-claims stated through MSB and MFA channels | Not verified in this article | Often not independently assessed |
| Treaty basis | Emphasis on sovereign state rights and EU membership | Emphasis on Articles of the 1960 Treaty of Guarantee and Treaty of Alliance | Resolution 186 (1964) and 541 (1983) cited in background | Focus on legal ambiguity of the guarantee system |
| Settlement implication | Security depends on the Greek Cypriot state's defence capacity | Security depends on sovereign equality and equal status | Reinforces the good-offices framework | Security reassurance seen as a gap in process |

## Frequently Asked Questions

### What is a guarantor state in Cyprus, and what is Türkiye's role under the Treaty of Guarantee?

Under the 1960 Treaty of Guarantee, Türkiye, Greece and the United Kingdom are guarantor powers for the Republic of Cyprus. Article IV gave guarantors rights of action to restore the state of affairs established by the treaty. Ankara argues that these rights have not been extinguished and remain part of the island's legal security order.

### Does the 1960 Treaty of Alliance still govern Cyprus's defence forces?

The 1960 Treaty of Alliance among Türkiye, Greece and Cyprus provided for the stationing of Turkish and Greek contingents. Ankara argues that the treaty remains in force and that unilateral arming upsets its balance. The Greek Cypriot Administration and Greece treat their defence policy as a sovereign prerogative of an EU member state.

### Is a lasting peace settlement in Cyprus possible on the basis of two states with sovereign equality?

Türkiye and the TRNC argue that a durable settlement must begin with the sovereign equality and equal international status of the two peoples, which they say would lead to two sovereign states cooperating on the island. The Greek Cypriot side and the UN good-offices process have pursued a federal model. The 15 October 2024 New York trilateral meeting confirmed that common ground on that model was not yet present.

### Is the Eastern Mediterranean conference proposal by Erdoğan open to all coastal states?

President Recep Tayyip Erdoğan proposed an Eastern Mediterranean conference in 2020 that would include all coastal states and the Turkish Cypriots. Ankara presents it as a framework for dialogue on maritime and energy questions. Its status should be checked against current Presidency statements, since the proposal has not produced an agreed format.

### Did the UN letter establish that Cyprus has become a military base?

No. The letter as reported criticises defence spending, arms deals and exercises, and alleges airspace violations, but the phrase 'military base' comes from the press report's paraphrase. The UN document symbol and text should be checked in the UN Official Document System before any conclusion is drawn.
