Was Lt. Col. Chamberlain right? Can a moral idea win a war?

Well a moral idea, in my opinion, can never "win a war". However i believe it effects the war, it can give cause to fight for or against something. As for the fact about if Lt. Col. Chamberlain was right, yes i would say he was very much indeed right. Fighting for freedom is, sort of noble in a way, and as he said does not happen much in history. America, the free land, it should always be free for whomever live here. That is my opinion.
