The US thinks as it does because of tyranny and oppression. One of the arguments against gun control and the 2nd Amendment is that it's designed to grant the people the physical power to overthrow government should it run rampant.|
"That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
You can argue the above has already been tested once before by the Civil War - it wasn't just a battle of slavery, but a battle of individual/state liberty vs federal law. But you can also argue that it's probably at the stage now where it's kind of an impossibility to rebel and revolt against the government, mostly because of the sheer size of the population.
Basically, the pursuit of liberty and individual freedom is the cornerstone of the whole US society and culture, although arguably it's not exactly relevant in a modern context. It forms more of an ideology than an actual cemented goal nowadays (to most sane people, anyway).
