What happened to good old fashioned war

i give it another month tops before war with at least iran, and possibly syria too. although i have supported the war in iraq until now, i think its time to leave and deal with the people that are actually gonna kill us.

and to address the thread topic, what happened to the days when you didnt need to justify war? gone are the days when leaders like ghengis kahn and alexander the great could invade any number of countries just because they felt like it. i think we need to apply this attitude to our foreign policy. we need to stop trying to protect everyone in the world and look after some of our own interests. 70% of the world's remaining oil is in iran. we need to get over ourselves and just take over their country and oil interests. we cant keep trying to overthrow regimes that hate us and put puppet democratic governments in their place. we need to start destroying, leaving these countries that harbor terrorists in ruins. when they start to rebuild, knock them right back down. we also need to stop crying about the civilians that die in wars. its a war, people die, get over it. if we dont kill them, they will kill us. just because these people you see on tv with their houses destroyed arent actually carrying guns or in the military doesnt mean they wouldnt kill you if they had the chance. they arent as innocent as you think. armies like Hezbollah hide behind their civilians because they know oppsing armies wont risk the civilan casualties. they fire rockets out of people's houses so when the enemy fires back they can bitch about civilians dying. in ancient wars, most civilians were killed. even after they defeated an enemy, the army would just burn the villages and kill people for no reason. they raped the women and took the survivors as slaves. im not saying we have to go that far, but i think we have to put in perspective how war operated for the majority of history.
