==Prelude. ==This paragraph was inspired by Noam Chomsky [https://www.youtube.com/watch?v=e1pNz8A5vMA talk] on Just War Theory. It meant to establish the ''[http://en.wikipedia.org/wiki/Jus_ad_bellum jus ad bellum]'' (the right to go to war). In his talk, Chomsky didn't give any justification to go to war and critisized the theory. Athough I a gree with Chomsky in amny ways, I still think we should find a theory that will be able to say when it is just to go to war. In this page, We will try to astablish, moral justifications for going to war, if such exists.
