“First, we didn't know ourselves. We thought we were going into another Korean war, but this was a different country. Secondly, we didn't know our South Vietnamese allies.

So, until we know the enemy and know our allies and know ourselves, we'd better keep out of this dirty kind of business. It's very dangerous.”
