Marshall Islands

States with nuclear-free security strategies

The Marshall Islands voted in favour of adopting the TPNW at the UN Diplomatic Conference on 7 July 2017, but has not yet signed or ratified it. The Marshall Islands’ hosting of US missile tests at Kwajalein Atoll means that it is not in compliance with the TPNW’s prohibition on assisting illegal activities relating to nuclear weapons.

Latest developments and background

The Marshall Islands abstained on the UN General Assembly resolution on the TPNW in 2018. The Marshall Islands’ foreign minister John Silk has said that his government cannot back the TPNW without US involvement, but has also communicated that ongoing internal consultations have prompted the government to take more time for consideration before joining the Treaty (The Marshall Islands Journal, vol. 49, no. 44 (2 November 2018)).


  • The Marshall Islands should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty.
  • The Marshall Islands should request that the United States cease the testing of nuclear-capable missiles at Kwajalein Atoll.
