Jersey, the saying "Same sh*t, different day" comes to mind. During ol' WW II, the German government was responsible for the wholesale slaughter of approximately 4 million innocent people. During Stalin's reign, Russia eliminated 10 million. The Japanese conducted ethnic cleansing campaigns throughout China. The current enemy has done little to compare with the evil that was brought on by those three countries.
Do you think that all of these countries followed the Geneva conventions? Japan didn't, and Russia sure as hell didn't. Germany and the U.S. followed them closer than most countries. The only thing the Taliban and AQ bring to the table that the others didn't, is their unconventional style of warfare. They have a command structure, they have training camps, internal government. . .they aren't all just a group of street thugs, or they would have been beaten long ago by the Soviets. I don't feel as if the game has changed. We just run a few new plays, that's all.
