Robert Kagan, one of the intellectual architects of the Iraq War, is swooning over Obama’s speech. That’s scary:

I don’t know what to say about an “Obama doctrine,” because based on this speech, I think we are witnessing a substantial shift, back in the direction of a more muscular moralism, a la, Truman, Reagan. the emphasis on military power, war for just causes, and moral principles recalls Theoedore Roosevelt’s phrase, “the just man armed.” There is something much more quintessentially American and traditional about this speech, compared to most of his rhetorical approach throughout the year.

Also see this from the same Politico roundup from Walter Russell Mead, Henry A. Kissinger senior fellow for U.S. foreign policy at the Council on Foreign Relations:

Barack Obama’s acceptance speech for the Nobel Peace Prize was a carefully reasoned defense of a foreign policy that differs very little from George Bush’s. He is winding down one war, escalating a second, and stepping up the pressure on Iran. He is asserting America’s sovereign right to unilateral action in self defense while expressing the hope that this right will not need to be exercised.
