USA is first and foremost a federation of relatively free countries, most legislation is at state level and it works in a way like EU with an integrated military. The major difference is they used to have freedom to choose healthcare, it is not forced like in EU (ex: in my country 10% of your income is paid as healthcare tax and you can be treated in state owned hospitals when there is a place available; note there is no obligation for the state to give you any care, but you go to prison if you don't pay up).
