Germany Resists Global Nuclear Ban Despite Growing Political Pressure

A global treaty banning nuclear weapons has gained steady support since its adoption in 2017. The Treaty on the Prohibition of Nuclear Weapons (TPNW) entered into force in January 2021, with nearly half of all UN member states now backing it. Yet key nations, including Germany, remain outside the agreement due to military alliances and strategic concerns.

The TPNW was first approved by the UN General Assembly in December 2016. After months of negotiations, 122 out of 193 member states voted in favour of the final text in July 2017. The treaty took legal effect on January 22, 2021, once 50 countries had ratified it.

By September 2022, 99 states had either signed, ratified, or acceded to the agreement. The treaty bans all activities related to nuclear arms, including development, possession, transfer, and use. However, none of the world’s nuclear-armed states or NATO members have joined. Germany has faced growing pressure to reconsider its position. In 2024, 127 members of the Bundestag signed a declaration calling for the elimination of nuclear weapons and urging the government to sign the TPNW. Yet officials have repeatedly cited NATO obligations as a barrier. Recently, SPD deputy leader Siemtje Möller even suggested Germany could contribute to a European nuclear deterrent, sparking further debate. Despite these discussions, the global nuclear stockpile continues to grow. By 2024, declared arsenals exceeded 12,000 warheads, reversing years of gradual reductions.

The TPNW remains a divisive but influential agreement in global disarmament efforts. While support among non-nuclear states has grown, major powers and their allies—including Germany—still refuse to join. The treaty’s long-term impact will depend on whether more nations shift their policies amid rising nuclear tensions.
