United States

Nuclear-armed state

6,185 nuclear weapons

1,030 nuclear tests

Has not yet joined TPNW

The United States can launch its nuclear weapons from missiles, submarines, and airplanes. Its intercontinental ballistic missiles are based in silos in Montana, North Dakota and Wyoming. It was the only country to use two nuclear weapons in war, on Hiroshima and Nagasaki in 1945. It also conducted 1,030 nuclear tests between 1945 and 1992, most of which were conducted in Nevada and the Marshall Islands, but some of which were conducted over the Malden and Kiritimati islands, Alaska, Colorado, Mississippi, New Mexico and over the Atlantic Ocean.

The United States did not participate in the negotiations of the Treaty on the Prohibition of Nuclear Weapons and has not yet signed or ratified it.

The United States voted against a UN General Assembly resolution in 2019 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”.

The United States 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.

In 2016, the United States 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”.

The United States actively discouraged other states from supporting the resolution.

In a “non-paper” sent to members of the North Atlantic Treaty Organisation (NATO) ahead of the vote, the United States “strongly encourage[d]” members 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”.
