"which is no different then any country that ever existed since the beggining of man."
so that makes it ok? Yes throughout history everyone did that, but no one ever learns from it, they probably came up with the same excuse you just gave me.
Plus, if you plan to go with one side in a conflict then you should face the consequences when the other side still holds a grudge.
Here is a situation:
A country is at civil war. Instead of supporting the 'right' side and making the 'wrong' side even angrier why not help in other ways? Support the innocent civillians, build hospitals, send food and clothing. And stop any dealing with the two sides. Ignore them untill they realize what they are doing is not accepted in the world-wide society. There are many ways to help in conflicts than just sending an army and forcing a peace, because it does not always work. This would cutdown on breeding terrorism atleast.
