I believe there is some middle ground between the two of you (orathaic and Hannibal).
I do agree American foreign policy is one of the most terrible and perverse things of the past 70 years. You might not care about the people in Grenada, or about the people in Guatemala, or about the people in Lebanon, though that makes you a terrible person, if those incidentes were isolated. But when you consider these, along with Chile, Argentina, Brazil, Paraguay (and earlier Colombia and Venezuela and, at some point, the vast majority of Latin America), Iran, Vietnam, South Africa (remember who backed the apartheid regime?), etc., it becomes absurd to defend American foreign policy as something good to its neighbours and 'partners'.
It is absolutely unacceptable for a country, especially one who claims to stand for freedom and democracy, to topple so many democratically elected governments to foster its own interests against those of the said countries. Like, really, it requires incalculable doublethink to accept these actions as 'reasonable'.
However, while I loathe all those responsible for these atrocious, however swift, actions, one can't atribute them to the US being a singularly evil nation.
All Great Powers, from the Romans to the British Empire a century earlier, would seek similar objectives. It just happens that it was deemed acceptable, say, in 1898, to invade Sudan as Lord Kitchener did, or to invade Afghanistan when the British did, while it rightly generated an outrage when the Soviets went there, or when the American invaded Iraq.
The Americans just happen to do it more efficiently. For comparison, how successful was the British attempt to oust Nasser, in 1956? And how effective was the ousting of Mossadegh three years earlier? More importantly, was there a general outcry when American-sponsored coups deposed democratically elected left-wing presidents in Brazil and Chile, in 1964 and 1973, respectively? What was, on the other hand, the reaction to the Soviet invasion of Czechoslovakia in 1968?
Obviously, Russian imperialism was no better than American imperialism, in several senses, but it is somewhat perverse that the CIA managed to orchestrate things so subtly that large parts of the affected countries populations's continued to see the US as a friendly partner, and not as the very nation responsible for pushing its own development, freedom and independence back.
However abhorrent that is, though, it's hard to argue Soviets would have been kinder, or Chinese will be friendlier. Unless we (meaning general population) manage to change how we see the world, in terms of moving our differences and all sorts of aggressive nationalism aside, and become overall way more peaceful and concerned about political and economic issues, it's unreasonable to expect Great Powers to behave differently.
Thus, not only it becomes clear, in the absence of radical change in people's mentality towards a wide variety of things, that any other nation in such a position would behave similarly, but it should also be noted that it could hardly be good if the US simply vanished from the world scenario, as that would simply give room to China and Russia to fill that gap. It seem having this sort of counterpoint makes things less terrible, in general.
