GUEST, warrior cultures have always caused violence around the world. The Romans did. Alexander the Great did. Genghis Khan did. And so on. Nothing new or ground-breaking in that.

Did war ever produce more overall (for both victor and vanquished)benefit than the losses incurred? Mmmm, dunno but I doubt it.

Conflict (not just war) can focus energies towards new solutions, which can produce benefit. But to keep the balance sheet profitable, conflict has to remain non-damaging, non-destructive.

Does the US have a militarist, "greedy warrior" culture, as you say? I can't see it. A gung-ho culture, yes in part. A "strongest is right" culture, yes in part again. A "me first and damn the good of the many" culture, yes in part once more. I won't tar everyone who has a US passport with the same brush, but the overall signals are there. But militarist? I don't think so. This is not a latter-day Sparta.
