My answer here is essentially the same as in my other comment, so I'll keep it short. You claim that the USA didn't help this country, say, but you have only the USA's word for this, which is unreliable to some.

Occam's Razor here reduces to a prior belief that the USA generally tells the truth, versus no such belief. Think of an American, a European, a Russian, and a Chinese.
