Our government kills people "over there" for a lot of reasons. Mainly because if you spend a ton of money to make sure any conflict happens there and not here, you actually save money by not having conflicts here- and conflicts that don't blow up your own buildings can be pretty lucrative on their own.

The question, though, is where the problem lies. There's all sorts of unwanted behavior. Generally, we don't prevent them in the most efficient ways, but in ways that make money for someone influential.
