Passage: Because of its neutrality policy, the Swiss army does not currently take part in armed conflicts in other countries, but is part of some peacekeeping missions around the world. Since 2000 the armed force department has also maintained the Onyx intelligence gathering system to monitor satellite communications.Following the end of the Cold War there have been a number of attempts to curb military activity or even abolish the armed forces altogether. A notable referendum on the subject, launched by an anti-militarist group, was held on 26 November 1989. It was defeated with about two thirds of the voters against the proposal. A similar referendum, called for before, but held shortly after the 11 September attacks in the US, was defeated by over 78% of voters.Gun politics in Switzerland are unique in Europe in that 29% of citizens are legally armed. The large majority of firearms kept at home are issued by the Swiss army, but ammunition is no longer issued.
