From an e-mailer:

On “Sixty Minutes”, Kerry stated that it only took him two weeks in Vietnam to realize that the war was wrong. It took more than two weeks in Vietnam to get used to the weather, and there was an orientation period for everyone that lasted that long. The politics and confusion of Vietnam took much longer than two weeks to grasp for anyone. Kerry was trying to pass himself off as an astute observer but came off sounding like someone who jumped to conclusions based on nothing more than cynical observations. He’s a Monday morning quarterback who’s trying to convince everyone he could have won the game on his first possession.
