Switzerland’s neutrality vote is asking the wrong question

Swiss voters will decide on September 27 whether to lock a tighter definition of neutrality into the constitution. Backers of the initiative want a strict rule that would bar cooperation with military alliances unless Switzerland itself is under attack or threatened with attack, and would prevent the country from imposing sanctions on a belligerent state unless the United Nations Security Council approved them. Polling suggests a majority currently plans to reject the measure, which would largely preserve the flexible, case-by-case neutrality Switzerland has practised in recent decades. Supporters say the proposal restores a traditional model of neutrality that has been central to Swiss identity since the European powers recognised its permanent neutral status in 1815. Opponents and many analysts counter that a constitutional restriction could force Bern to roll back existing sanctions on Russia and limit recent bilateral security cooperation—cyber, air-defence and joint exercises—with neighbouring NATO members that Switzerland expanded after 2022. Beyond the immediate legal change the referendum would make, three developments since 2022 complicate Switzerland’s strategic environment. First, the character of the threat has shifted: Switzerland’s historical focus on deterring territorial invasion is less suited to risks such as missiles, drones, espionage and sabotage that cross borders or target critical infrastructure without conventional troop movements. The 2026 Swiss Security Policy Strategy warns of a "window of vulnerability" emerging around 2028 as Russia rebuilds military capacity while Europe re-arms. Second, relations with major economic partners have become less predictable. In 2025 the United States imposed a 39% tariff on many Swiss exports; that tariff was later reduced to 15% after negotiations and Swiss investment commitments. The episode illustrated that neutrality did not insulate Switzerland from punitive trade measures driven by a partner’s national interests. Third, economic ties with China have grown: Swiss-Chinese goods trade exceeds 50 billion Swiss francs a year when gold is included, and negotiations on an upgraded free-trade agreement concluded in August 2026 would make 99.8% of current Swiss exports to China tariff-free—raising the economic stakes of any possible future policy conflict with Beijing. Those shifts mean the referendum may be addressing the wrong question. Even if voters reject the constitutional restriction and retain flexible neutrality, Switzerland will still need to find ways to secure itself against non-territorial threats, diversify economic relationships, and calibrate cooperation with neighbours and partners without surrendering the diplomatic space neutrality provides. A formal change to the definition of neutrality would not by itself solve these strategic challenges, and may reduce options Switzerland could need as Europe’s security environment evolves.
