Swiss neutrality referendum could bar Russia sanctions and limit NATO cooperation

BERN, Switzerland — Swiss voters are preparing to decide whether to write a stricter form of neutrality into the constitution, a move that could prevent the government from joining sanctions against Russia and curtail its growing defense cooperation with NATO and neighboring European states.

The conservative-led initiative would require Switzerland to maintain “permanent and armed” neutrality. It would bar the government from joining economic sanctions unless they were unanimously mandated by the United Nations Security Council — an uncommon outcome because permanent members, including Russia and China, hold veto power. It would also block deeper integration with foreign military alliances.

The vote follows a break with decades of Swiss diplomatic precedent. After Russia’s full-scale invasion of Ukraine in February 2022, the Swiss Federal Council matched the European Union’s sweeping sanctions packages against Moscow. Switzerland froze billions of dollars in Russian financial assets held in Swiss bank accounts, banned luxury-goods exports and closed its airspace to Russian aircraft.

The alignment prompted widespread public protests in support of Ukraine in major Swiss cities. It also drew immediate outrage from traditionalists who said it damaged Switzerland’s reputation as an impartial global mediator. Christoph Blocher, the 85-year-old billionaire spearheading the neutrality campaign and an influential figurehead of the right-wing Swiss People’s Party (SVP), has argued publicly that Russia now sees Switzerland as an active participant in the conflict, undermining the security neutrality was meant to provide.

Blocher has spent decades opposing Swiss integration with international bodies, including Switzerland’s entry into the United Nations until 2002. The lobbying group “Pro Schweiz,” heavily backed by the SVP, submitted more than 130,000 signatures to force the referendum, drawing on domestic anxiety over Europe’s shifting security landscape. Under Switzerland’s direct-democracy system, a citizens’ group can bring a constitutional amendment to a nationwide vote by collecting 100,000 valid signatures within 18 months.

The Swiss Federal Council and center-left parties oppose the amendment, warning that a rigid constitutional definition of neutrality would isolate the country and compromise its moral standing. Fabian Molina, a Social Democrats member of parliament, has cited Switzerland’s refusal to join international sanctions against apartheid-era South Africa as a warning. Critics have long noted that Swiss banks and businesses, including entities linked to Blocher’s industrial empire, continued trading with Pretoria and used the neutrality policy to maintain profitable trade routes.

Molina and other opponents say the proposed sanctions ban would repeat those errors, making Switzerland a financial safe haven for sanctioned regimes and oligarchs. Defense analysts and military officials, meanwhile, warn that the vote comes as the Swiss military faces severe modernization challenges and new security threats.

Unauthorized drone flights have recently been detected near Swiss military installations and critical infrastructure. The incidents have raised concerns about whether a defense model built around a citizen militia and an extensive network of Cold War-era civil defense infrastructure can meet the demands of modern hybrid warfare, vulnerabilities highlighted by the war in Ukraine.

The government has sought deeper participation in NATO’s Partnership for Peace program and signaled interest in the European Sky Shield Initiative, a joint air defense project. The amendment would likely outlaw such partnerships and limit Swiss defense capabilities to the country’s borders, while military planners argue that European security is increasingly interdependent. Switzerland’s planned purchase of 36 F-35A fighter jets from U.S. contractor Lockheed Martin and five Patriot air defense missile units from Raytheon has also faced global supply-chain bottlenecks, rising costs and delivery delays.

The debate has highlighted a growing national consensus that 19th-century diplomatic structures may no longer be viable in a highly globalized, interconnected security environment. Switzerland’s neutrality was negotiated and imposed by major European powers at the 1815 Congress of Vienna to create a strategic buffer between France and the Austro-Hungarian Empire; the policy later insulated the alpine country from the devastation of both world wars.
