I think if you:
1. Strip away the mythology built up about the founding fathers, the constitution, the US revolutionary war, civil war, etc.
and
2. Separate the ideological/philosophical writing from some of the more enlightened figures in American history from the actual practice of government.
then
you find that the US government really was never more than an opportunity to strip away an existing aristocracy and to replace it with a new one. Sometimes that aristocracy has been more enlightened and benevolent, sometimes less so. Post WW2, it seems to be that there's been a big rush to minimize those two qualities and each administration seems intent on outdoing the prior.
I think it's utterly bizarre that the ruling class is basically manufacturing a threat of violence to react against now. It seems that the vast majority of stuff being "caught" that I read about are just government entrapment operations. The "threat" but lack of any successful actions leads me to believe that it's just about all due to government agents/provocateurs finding the sort of people they can goad into action and immediately bust rather than any actual threat of terrorism, domestic or otherwise.
