Swiss Voters to Decide on Tighter Neutrality and NATO Cooperation
Swiss voters will decide whether their country should follow stricter rules about staying neutral.
The vote is scheduled for September 27.
Supporters want Switzerland to avoid military cooperation with NATO and most economic sanctions.
They say Switzerland became less neutral when it sanctioned Russia after the invasion of Ukraine.
They also say being clearly neutral could help keep Switzerland safe.
The government and most political parties disagree.
They say the new rules could make it harder for Switzerland to protect itself and work with nearby countries.
A government official said neutrality is already clearly understood and does not need to be rewritten.
Recent polling showed more people against the proposal, although the campaign could still change voters’ minds.
A September 27 referendum would bar Switzerland from imposing sanctions or cooperating with NATO unless specific conditions apply.
Supporters, including the Swiss People’s Party, say sanctions on Russia have eroded Switzerland’s neutrality.
The proposal would prohibit military-alliance cooperation unless Switzerland is attacked and restrict sanctions not approved by the United Nations.
The Swiss government and most political parties oppose the measure, warning it could weaken national security and relations with neighbors.
One poll showed 62% opposed and 36% in favor, though campaign spending could narrow the gap.
