1) Middle initial. This is very executive branch, if you ask me.
2) His unwillingness to finish out his Air National Guard stint tells us he's a man who doesn't let himself be sidetracked from reaching his goals and realizing his dreams. This also means he may be less emotionally averse to the prospect of war, since his objectivity is untainted by personal experience in armed conflict. But we may never know.
3) His familiarity and friendliness with powerful people in Saudi Arabia have certainly precluded the possibility that rich Saudis could fund terrorism against the USA. I'm sure we would know right away who's giving support to terrorist organizations, and Bush would definitely have the culprits and their families ostracized by the good peaceful Saudi people. In addition, our constructive engagement in the political milieu of the Arabian peninsula has certainly helped democracy and human rights flourish there.
