Modern warfare doesn't force you to see the enemy die. Modern warfare include to cripple the source of revenue, which includes civilians. Modern war is about Total war, where nobody escapes and everyone participates, regardless if you like it or not.

Very few people are able to kill another human and hold him in your arms and look in to his eyes while he is dying. If you get a bomb off and you only get some flashy news pictures on TV, it's much less real and it's easier to lie to your selves and justify it.

Unfortunately a human life has very little value these days.......
