Swiss voters have overwhelmingly rejected a proposal to introduce stricter constitutional limits on the country’s longstanding policy of neutrality, with 70.15% voting against the initiative in a referendum on September 27, 2026.

The “Safeguard Swiss Neutrality” initiative received 29.85% support and was rejected in all 26 cantons, according to official results from Switzerland’s Federal Statistical Office. Voter turnout was 47.06%.

The result leaves Switzerland’s current approach to neutrality largely unchanged, allowing the government to impose sanctions, cooperate with international security partners and maintain limited cooperation with NATO while remaining outside military alliances.

Initiative for Stricter Neutrality

The proposal, promoted by the Pro Switzerland organization and backed by the right-wing Swiss People’s Party (SVP), sought to write “perpetual and armed” neutrality directly into the Swiss Constitution.

It would have restricted Switzerland from joining or cooperating with military and defense alliances unless the country was attacked or faced an imminent attack.

The initiative also sought to limit Switzerland’s ability to impose sanctions on states involved in wars. Such measures would generally have been allowed only when authorized by the United Nations Security Council.

Supporters argued that these restrictions were necessary to protect Switzerland’s traditional neutrality and preserve its role as a mediator in international conflicts.

They particularly criticized Switzerland’s decision to adopt European Union sanctions against Russia following Moscow’s full-scale invasion of Ukraine in 2022, saying the policy had weakened the country’s neutral position.

Government Opposed the Proposal

The Swiss government, parliament and almost all major political parties opposed the initiative. They argued that a rigid constitutional definition would reduce the government’s ability to respond to international crises and limit cooperation with other countries on security issues.

Switzerland is not a member of NATO, but it has cooperated with the alliance for decades, including through the Partnership for Peace program and other security activities. The government argued that maintaining flexibility was important as Europe’s security environment changes.

The referendum therefore did not ask voters whether Switzerland should remain neutral. Instead, it focused on how strictly neutrality should be defined and how much freedom the government should retain when applying the policy.

Ukraine War and Debate Over Neutrality

The debate over Swiss neutrality became sharper after Russia launched its full-scale invasion of Ukraine in 2022. Switzerland, despite its neutral status, adopted broad EU sanctions against Russia. The decision drew criticism from Moscow and from Swiss political groups that support a stricter interpretation of neutrality.

Supporters of the referendum argued that Switzerland should not impose sanctions on countries involved in wars unless the United Nations Security Council approved them.

Russia holds a permanent seat and veto power on the Security Council, meaning the proposed rules could have significantly restricted Switzerland’s ability to impose sanctions against Moscow.

The government instead maintained that sanctions and other measures could be compatible with neutrality while allowing Switzerland to respond to violations of international law.

Switzerland has been internationally recognized as a neutral state since 1815, following the Napoleonic Wars. Neutrality has also formed part of the country’s constitutional framework since the establishment of the modern Swiss Confederation in 1848.

The policy does not mean Switzerland is completely isolated from international affairs. The country maintains armed forces for national defense, works with international organizations, and has participated in peacekeeping and security cooperation. Switzerland also joined the United Nations in 2002.

Its current policy allows cooperation with other states on security matters while keeping the country outside military alliances. The referendum would have placed tighter constitutional limits on that approach.

Clear Rejection Across Switzerland

The rejection was broad across the country. The “No” vote exceeded 70% in several cantons, including Bern, Zurich, Basel-Landschaft, Jura, Lucerne, Solothurn, Vaud, Neuchâtel and Zug.

The result was closer in some areas, including Ticino, where 51.75% voted against the initiative. However, the proposal failed to win a majority in any canton.

The initiative therefore fell short of both requirements needed for a constitutional amendment: a nationwide majority of voters and a majority of the cantons. The SVP has accepted the result and said it currently has no plans for immediate further action.

Room for Policy Changes

The referendum leaves Switzerland with its existing approach to neutrality. The government can continue to impose sanctions, including those targeting Russia, and maintain security cooperation with NATO and European countries without joining a military alliance.

The vote also leaves future governments with greater room to adjust how neutrality is applied as European security conditions change.

The result does not end the debate over Switzerland’s role in European security. Questions over defense policy, relations with NATO and the European Union, sanctions and arms exports are likely to remain part of the country’s political debate.
