We have a moral obligation to help people that are being oppressed by evil dictators. And we need to do something about it. We can't police everything, but we can pick and choose the ones. It is sometimes the case that countries are run by groups of thugs who can basically be toppled by just sending and disciplined troops. There was a rampage east temor in 19 99. An australian sentin disciplined troops, the rampage stopped. So if you're dealing with basky thugs or criminal or forces like that, they can be toppled, sometimes by simply showing up to a degree.
