First it has frequent binding referendums so there is no political elite, PPE based class system. All citizens are genuinely equal. The latest two referendums show this.
Note the first June referendum was highly technical and would have taxed the limited intellect of our corrupt duck house obsessed MPs but the Swiss voters coped easily.
Second all male citizens up to age 50 do 2 weeks refresher military training each year.
Third they keep their weapons and ammo at home.so any armed IRA style attack can be resisted by the law abiding citizens carrying arms as per the second amendment to the US constitution
Fourth they never get involved in foreign wars and get their children killed as we did with war monger Blair
Finally they have always rejected joining the EU Fourth Reich.
Why can't we accept the Swiss have a better more democratic political system than we have. Ours is creaking at the seams and serves only the UK political and social elite. It was invented almost 400 years ago when few could read or write. Trump governs the US and the free world by Twitter. Surely this is better and more open than the 1922 committee.
Despite being armed to the teeth Switzerland has a very low murder rate. Every road tunnel is mined in case of invasion. If you want peace prepare for war.and get rid of our politicians in Lords and Commons.
