Swiss voters are poised to reject proposed constitutional changes that would restrict the country's ability to cooperate with NATO or impose sanctions on other nations, according to two recent polls. The referendum, scheduled for September 27, aims to codify a stricter definition of Swiss neutrality.

The outcome of the referendum will determine Switzerland's future foreign policy flexibility, impacting its ability to engage in international security cooperation and respond to global crises, potentially affecting its standing as a mediator and its defense posture.
Voters in Switzerland are expected to reject proposed constitutional changes that would impose a stricter definition of the country's neutrality, barring cooperation with NATO and the imposition of sanctions on other nations. Two polls released ahead of the September 27 referendum indicate a clear majority against the initiative launched by the right-wing Swiss People's Party (SVP).
A survey by 20Minuten and Tamedia found that approximately 68% of voters intend to reject the proposals, with only 31% in favor. A separate poll conducted by GFS Bern for broadcaster SRG showed 63% against the initiative and 34% in favor. Both polls indicated a rising opposition to the changes, which have been opposed by the Swiss government.
Swiss neutrality, recognized internationally since 1815 and enshrined in the constitution since 1848, has historically kept the country out of global conflicts. Christoph Blocher, a prominent SVP politician, argued last month that Switzerland's neutral status was threatened after the government imposed sanctions on Russia following its 2022 invasion of Ukraine.
Supporters of the proposed changes contend that tightening the constitutional definition of neutrality would prevent the government from diluting it and would help Switzerland maintain its role as a credible mediator. However, opponents argue that the initiative would significantly limit Switzerland's ability to respond to foreign policy challenges and would weaken its defense capabilities. Nearly a quarter of respondents in the Tamedia poll suggested that refusing to impose sanctions for violations of international law would be perceived as siding with aggressors and would harm Switzerland's global reputation.
