As far as controlling what other countries do, I would say don't be naive. We not only have the responsibility to do so, but the burden of making the right call for the sake of the world. That you and others don't want us to have that responsibility means little as to the fact that we already do.
Good point! We have been objecting, and we are ignored! Most sane people all over the world just want to live in peace - but decisions are made by those who don't always have their best interests in mind. They just don't seem to give a damn about collateral damage, but it does make enemies of those who suffer, and that's a given. I'd feel the same way! When pissing contests between leaders is allowed to become a game of "one-upmanship," look for trouble ahead for the little people - always!
