Switzerland votes on stricter neutrality
A popular initiative seeks to constitutionally restrict military cooperation and sanctions against states at war.
Swiss voters will decide on Sunday on an initiative that seeks to enshrine the country’s neutrality much more strictly. The outcome could affect Bern’s room to adopt European sanctions and cooperate internationally.
The vote concerns the ‘Preserve Swiss Neutrality’ initiative. It seeks to add to the constitution a provision stating that Switzerland maintains permanent and armed neutrality. The country would be barred from entering into or cooperating with military or defence alliances, except when Switzerland itself is attacked or an attack is immediately threatened.
The proposal goes beyond military cooperation. Under the wording of the initiative, Switzerland would not be allowed to participate in foreign wars or impose economic or diplomatic sanctions on states at war. Exceptions would apply to United Nations sanctions and measures intended to prevent sanctions from being circumvented.
The government is defending current practice. According to the Swiss authorities, neutrality is compatible with security cooperation and sanctions. After Russia’s invasion of Ukraine, the Federal Council decided in 2022 to adopt most European Union sanctions.
This means the ballot concerns not only a legal concept, but also a choice about the country’s foreign-policy direction. The initiative’s supporters believe that, by adopting European sanctions, Bern has moved away from its historic neutrality. They want to prevent Switzerland from becoming part of power blocs or conflicts between other countries.
Opponents, including most major political parties apart from the right-conservative Swiss People’s Party, warn instead of a loss of room for manoeuvre. They argue that a rigid constitutional formulation would make it harder to respond to new crises and maintain cooperation with European countries.
A poll cited by SWI swissinfo.ch in mid-September indicated a substantial lead for the opponents: 63 per cent said they were against the initiative and 34 per cent in favour. This is a poll, not a prediction of the result. Swiss referendums can also be influenced by turnout and regional differences.
In the event of a yes vote, it would first be necessary to establish how existing sanctions and international obligations relate to the new constitutional provision. The vote would also not immediately alter Switzerland’s candidacy as a mediator, but it could significantly reduce the room for future decisions.
One story, several perspectives
What is established
- Switzerland is voting on a constitutional amendment that defines neutrality more strictly.
- The proposal restricts military cooperation and participation in sanctions, with exceptions.
- The Swiss government and most major parties oppose the initiative.
Left
Arguments Neutrality must not become an excuse to look away from violations of international law. Switzerland must retain the room to support sanctions and take responsibility within European cooperation.
Values The international rule of law, solidarity with attacked countries and collective security.
Consequences A rejection would preserve the ability to exert pressure on aggressors and could support cooperation with European partners.
Centre
Arguments Neutrality has value, but must remain practical and adaptable. The constitution must not create an automatic blockade in every future crisis.
Values Institutional continuity, legal certainty and room for diplomacy.
Consequences Maintaining the current approach would prevent abrupt changes of direction, but leave the debate over the limits of sanctions policy unresolved.
Right
Arguments Switzerland must decide independently and not be drawn into international conflicts through the EU. From this perspective, sanctions and military cooperation undermine the credibility of neutrality.
Values National sovereignty, self-determination and restraint in foreign conflicts.
Consequences A yes vote could emphasise Bern’s independence, but would probably limit future cooperation with European countries.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
The content of the initiative, the vote on 27 September and the earlier adoption of EU sanctions are certain. The consequences of a yes vote for existing sanctions will have to be worked out legally; the poll is not a result.Sources
