>>54718871Switzerland is the world's only currently existing and also longest lasting confederacy.
CH for their websites, currency, and other official uses means "Confederacy Helvetica". The Helvetii were the original Gallic tribe living in the region.
Their government model is both centralized and decentralized at the same time. I'm not sure if it would work on a larger country.
About 5 years ago I was offered a job at an Engineering firm in Switzerland (I work in the firearms industry). I speak German and a little French, so it shouldn't have been too difficult a transition. I was initially interested in becoming a citizen. It takes a very long time and you have to take a test to prove that you are of Swiss culture, mentality, and outlook. In the end, I remained in the US.
