Slovakia

Umbrella state (NATO)

Slovakia boycotted the negotiations on the Treaty on the Prohibition of Nuclear Weapons (TPNW) in 2017 and has consistently voted against the annual UN General Assembly resolutions on the Treaty, including in 2024. Slovakia may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.

Latest developments

At the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) Preparatory Committee session in July 2024, Slovakia said that a world without nuclear weapons ‘remains our ultimate objective’. It noted, however, that the continued erosion of the global arms control and disarmament architecture and other negative developments in the nuclear domain are hampering ‘effective progress in nuclear disarmament’.1

In the First Committee of the UN General Assembly in October 2024, Slovakia said that Russia’s ‘irresponsible nuclear rhetoric’, its announced deployment of nuclear weapons on the territory of Belarus, its new nuclear doctrine and the revocation of its ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) ‘are escalatory and unacceptable steps’.2

Recommendations

  • Slovakia should renounce the possession and potential use of nuclear weapons on its behalf, and ensure that nuclear weapons do not have a role in its defence posture.

  • Slovakia should comply with its existing obligation under Article VI of the NPT and pursue negotiations in good faith on nuclear disarmament.

  • Slovakia should urgently adhere to the TPNW. Until it is in a position to do so, it should welcome the TPNW as a valuable component in the global disarmament and non-proliferation architecture, work with the Treaty's states parties on practical steps towards disarmament, and attend the meetings of states parties as an observer.
