care to elaborate on this?

I can't tell if you mean that most nation state espionage resources are spent keeping a watchful eye on the U.S. since they see the U.S. as aggressive and dangerous, or you mean that literally American citizens are aggressive and dangerous (i.e. perhaps due to prevalence of firearms with non-conformist, anti-government, anti-authority views), that the U.S. spends much of its own resources spying on its own citizens?
