President Obama has made it clear he is not afraid of doubt, and is comfortable with uncertainty. He uses his head, not his gut, and is very analytical. Such is his decision making style.
He is deliberative, methodical, and measured in his approach to decisions. He has held nine meetings with his cabinet, military advisers, and staff on Afghanistan over a period of two and a half months, and does not worry about criticism.
His approach is diametrically the opposite of the Bush-Cheney technique, described as Texas and Wyoming frontier cowboy and secretive.
Considering the disasters that the Bush-Cheney administration perpetrated, it is comforting that Obama is NOT using emotion to make decisions.
