"Now you tell me what kind of Commander in Chief disregards the advice of his top military advisors on his most important military decisions?"

I highly doubt it is as simple as blowing off their advice. You have to weigh your decisions based on as much info you can get and consider the source and their motivations. For example, look at JFK and the Cuban Missile Crisis. If he followed his war hungry military advisors, we may have ended up in a nuclear war and you and I probably wouldn't be debating this stuff today...
