The U.S. has made mistakes. The U.S. has also held the capability to annihilate the world several times over in the palm of its hands and has yet to use a nuclear weapon since WWII.
Now ask yourself what ISIS would do with the kind of power the U.S. wields. Yeah ... that's what I thought.
Again, I didn't say ISIS was good, but I'm also saying the US isn't good. The US wants to dominate the world, and knows that using nukes will set people against it.
ISIS might not use nukes were it in a position of power where it didn't feel threatened all the time.
Circumstances don't make ones actions morally better.
The US is evil.
The U.S. is evil. Haha. Good one. The U.S. has kept the world more free and more prosperous by far than China or Russia ever would have. You know, the only other super powers, kept in check only by the United States?
But shit, the U.S. seems to be deteriorating. Maybe you'll finally get your wish to live under a Chinese-led world. Maybe in a few decades you'll look back and think that the U.S. wasn't all that bad after all ...
Has it? How about Venezuela?
Democratically elected leader ousted in govt backed coup d'etat? Then managed to get back in power as the coup fizzled out. Does this make people "more free and more prosperous"?
How about Cuba? US sanctions against it for decades which impoverished the country so the US could say "hey, look, Socialism doesn't work".
How about OPEC countries. The US didn't like OPEC taking charge (under Chavez from about 2000 onward) so tried to get rid of Chavez, got rid of Hussein, got rid of Gaddafi, tried to get rid of the Iranian leadership and has had sanctions against Venezuela AND Iran for quite a while now.
How about supporting Pol Pot in Cambodia?
