So hat tip to BTD at Talk Left for the link to Matt Yglesias piece regarding the "Bush Doctrine". Unfortunately, for varying reasons, each author's post focuses on the Palin angle (Bashing Palin for Yglesias, combating PDS for BTD).
What is missing is exploring one of the reasons why people who aren't thrilled about Obama (to put it mildly) still could find a reason to vote for him over risking McCain in office: John McCain apparently believes in Bush's idea of prophylactic (he would call "preventive") war.
"...George W. Bush has outlined a doctrine that he calls “preemption” but that’s really prevention or “anticipatory self-defense.” It holds that we should attack other countries that might attack us at some future point even if we have no particular evidence of a specific or imminent plan to do so. As we also know, John McCain agrees with this doctrine."
I would like Yglesias to put up some links showing that John McCain agrees with what I would prefer to call "prophylactic" war. I prefer the term because it is not only dismissive, but also more descriptive, going to the heart of the lizard brain rationale which gives the "Bush Doctrine" appeal to the lizard brain set. A prophylactic is a barrier, a preventive barrier which prevents something "bad" from happening based on actions you are taking which if you didn't take, wouldn't happen. Preventive implies you may just be sitting there, minding your own business and all of a sudden "BAM" something bad happens to you. A prophylactic is only required when you are taking an action (like manipulating Middle East politics to ensure a steady flow of oil) which includes a risk of injury, or maybe "contamination". Another plus for the lizard brained.
My assumption is that Obama is not a prophylactic war adherent, and would not pursue a "Trojan" war (if you will since I couldn't resist) against Iran or North Korea, or even Russia (or it's surrogates).
That would be a powerful distinction between Obama and McCain, it would be at least if you believe Congress would be too chicken-hearted to restrain McCain....
