>>This meme is age old: http://en.wikipedia.org/wiki/On_War mentions Clausewitz' concept: "war is the continuation of politics through other means". This is about 180 years old.

I agree. We may ponder over "internally" here - internally conflicting as in "intrinsically contradictory" or "internally... in a society", just because someone may argue that war is between societies. But we can just define this as the global human society - within it conflicts exist, and for lack of smarter solution, people will fight.
