You say war is a necessity. However, under what definition of just war has the US deployed troops since WWII? It has all been old men sending young men to fight and die for their political ambitions, not defense of hearth and home.
You believe I attack your honor. I do not. I question your actions and their effects, regardless of your motivations. I question the model of the military. I question the politics behind military adventurism. Especially in a world where the military is not conscripted, it is the duty of the soldier to examine the premises and principles behind his choices and actions. But the military teaches obedience, not critical thought. This is a pitfall if the goal is defending freedom.
