I do know why NATO bombed Serbia. Often when it’s brought up, people neglect to mention why it happened. The result is we have thousands of people who believe NATO is evil because supposedly they’ll bomb cities for no reason.

But there is a reason, which curiously enough you neglected to mention. As the other commenter pointed out, it was to stop an active genocide which was being prosecuted by Slobodan Milosevic’s military and paramilitary forces.
