Actions speak louder than words. Saddam claimed he was a Muslims, but by his action he did things that Muslims would not do. I don't consider him to be a Muslim. Just because someone says he a Christian does not make it so. Hitler believed that it was his moral duty to destroy every Jew, does that make what he did moral?
Re Santorum and Iran. An open war is the last option, but still an option. Even President Obama has plans for going to war should the worst come to fruition. His "desire' for war is only the last option we take, not the first option. When you are the leader of a country you have far more on your plate than a citizen ever would. Going to war is not an action to be taken lightly and he certainly is not taking it lightly. Considering their clandestine operations of supporting terror organisation around the world, Iran does need to be harshly dealt with should they cross certainly lines. If you are not willing to stand up for what you believe in, then evil will take over the world.
