What is it Good For? -Mark O'Brien

What would the world be today if Hitler had been allowed to take over?  What would have happened if no one fought back against the Roman Empire, or Alexander the Great?  That is frightening to think about.  Millions more would have been imprisoned and killed.  The only people left would be Aryan. He could have killed Billions of men, women, and children.  Someone had to stop him and the Nazi Party.  Yes I completely agree that war is horrifying, but in most cases it is just and right.  If you don't think it is right I have a question.  Is it right to stand back and not do anything when ISIS is cutting the heads of children off?  It seems the US has acquired the responsibility of the global police force.  We were the leading force in WW2, Vietnam, Iran, Iraq, and now with ISIS.  Should we be rewarded for taking down regimes of oppressors... I think so.  The more effective they get the easier it is for the world to end.  I don't know if I want war to become more effective because now with nuclear weapons the would could be gone within a matter of hours.  Einstein said, "I know not what weapons WW3 will be fought with, but WW4 will be with sticks and stones."
