I think it is a thing of "the lesser evil", A "seemingly" lesser evil. Those who are critical of the US and the West, like my father, tend to overlook the evils of rival powers, the same goes the other way around.
The thing is, the alternative, seeing all great powers for what they are: equally deplorable evils (as I do), is fucking depressing. It makes you think there's no hope because the world is at the mercy of the biggest pieces of shit ever, a war between Monsters and Demons.
So you want me to take a Shower all naked in the rain?
