There will always be a Hitler, a Stalin, a Bin Laden. When they come knocking you better hope there are rough men ready to do violence on your behalf as Kipling said.
So true.
War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions, and blood of better men than himself. --John Stewart Mill--
