Blog entries: Switzerland

Although Switzerland voted in favor of the adoption of the Treaty on the Prohibition of Nuclear Weapons (TPNW), it did not join the TPNW. Joining the TPNW in the current international context could entail risks in terms of both the Swiss nonproliferation diplomacy and Switzerland's security policy interests. In April 2019, the Swiss government announced that by the end of 2020, it would review the situation around the TPNW. However, by December 27, 2020, no revision was made, which might mean that the Swiss government did not change its mind and does not want to join the Treaty. However, pressure from both houses of the Swiss parliament and NGOs and entry into force of the TPNW may influence the Swiss government's position on the issue.
