Nuclear-weapon endorser: hosts nuclear weapons on its territory

20 U.S. nuclear weapons hosted

Did not participate in TPNW negotiations

Has not yet joined TPNW

Belgium is one of the five NATO states to host U.S. nuclear weapons as part of NATO's nuclear sharing agreement. The Belgian air force is assigned approximately 20 B61 nuclear bombs, which are deployed at Kleine Brogel Air Base.

Belgium has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. It did not participate in the negotiation of the treaty at the United Nations in New York in 2017 and thus did not vote on its adoption. 

A public opinion poll conducted by YouGov in April 2019 found that 64 per cent of Belgians believe that their government should sign the treaty, with 17 per cent opposed to signing and 19 per cent undecided.

In September 2018, more than 150 Belgian mayors signed a letter to the Belgian government and parliament calling for Belgium’s signature and ratification of the treaty.

Belgium voted against a UN General Assembly resolution in 2018 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.

In 2016, Belgium voted against the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

In a “non-paper” sent to NATO members ahead of the vote, the United States “strongly encourage[d]” members, including Belgium, to vote against the resolution, “not to merely abstain”. In addition, it said that, if the treaty negotiations do commence, allies and partners should "refrain from joining them”.
