It means they want the war to come, because they see no other way, and are not willing to accept an alternative. War hawks make war. You can call me a war hawk, but you can't say I want war. I know more than most people, in that I know what is worth fighting for. War is a stupid thing.
Many people die in war.
And in most wars they die for nothing. But some wars are different. Sometimes there is a reason to fight. Sometimes there is a Reason for war. In this type of war, yes, people do die.
