Yeah, the Israelis showed their stuff in the six day's war, for sure, but don't forget, the first time we went into Iraq, the ground war took four days and four hours (100 hours) and our casualties were...what...a few dozen? Iraqi casualties were in six figures!
Granted, that was after a month of softening up via air assault, but still...anything the Israelis can do, we can do better, if we really set our minds to it.
