Apart from the pre-emptive reason for starting the war, another "excuse" the US has been throwing around in the last couple of years is Humanitarian (note: the Sudan). Hey, this country is suffering, we should go in and bomb the hell out of it, put in a puppet regime and suck all the oil out, for humanitarian reasons, of course.

the only reason for an invasion is when many countries from the UN do it as a peace keeping mission, with mutual agreement.

under Article 51 .. the specific authorization of force by the Security Council as a last resort to maintain international peace and security, under Chapter VII.

and yep, bb, talk about your opinions, but when you put a lot of false words into other people's mouths, thats bigotry, arrogance, and offensive.
