definition seems to fit. What else should I call it?
It's a concept that's been around ever since there have been people in charge safely away from the carnage who have at their disposal young and fresh bodies to throw at their paranoid or imperialistic schemes.
Chickenhawk, Armchair Warrior, blustering militaristic bag of wind. I could care less what you call it. The definition is a valid one in all societies and generally is not considered a badge of honor.
What's unique about the ideal though is that, no matter what one believes about the right or wrong of using warfare to further foreign policy, the (insert label here) gets to implement their plans with little personal sacrifice and thus it really can't be viewed without some suspicion regarding motives, greed, and fear.
