Obama's perspective draws on that of the critics of the Cold War strategy of active balancing, who maintained that without a major Eurasian power threatening hemispheric hegemony, U.S. intervention is more likely to generate anti-American coalitions and precisely the kind of threat the United States feared when it decided to actively balance. In other words, Obama does not believe that the lessons learned from World War I and World War II apply to the current global system, and that as in Syria, the global power should leave managing the regional balance to local powers.
Romney and Active Balancing
Romney takes the view that active balancing is necessary. In the case of Syria, Romney would argue that by letting the system address the problem, Obama has permitted Iran to probe and retreat without consequences and failed to offer a genuine solution to the core issue. That core issue is that the U.S. withdrawal from Iraq left a vacuum that Iran -- or chaos -- has filled, and that in due course the situation will become so threatening or unstable that the United States will have to intervene. To remedy this, Romney called during his visit to Israel for a decisive solution to the Iran problem, not just for Iran's containment.
Romney also disagrees with Obama's view that there is no significant Eurasian hegemon to worry about. Romney has cited the re-emergence of Russia as a potential threat to American interests that requires U.S. action on a substantial scale. He would also argue that should the United States determine that China represented a threat, the current degree of force being used to balance it would be insufficient. For Romney, the lessons of World Wars I and II and the Cold War mesh. Allowing the balance of power to take its own course only delays American intervention and raises the ultimate price. To him, the Cold War ended as it did because of active balancing by the United States, including war when necessary. Without active balancing, Romney would argue, the Cold War's outcome might have been different and the price for the United States certainly would have been higher.
I also get the sense that Romney is less sensitive to global opinion than Obama. Romney would note that Obama has failed to sway global opinion in any decisive way despite great expectations around the world for an Obama presidency. In Romney's view, this is because satisfying the wishes of the world would be impossible, since they are contradictory. For example, prior to World War II, world opinion outside the Axis powers resented the United States for not intervening. But during the Cold War and the jihadist wars, world opinion resented the United States for intervening. For Romney, global resentment cannot be a guide for U.S. foreign policy. Where Obama would argue that anti-American sentiment fuels terrorism and anti-American coalitions, Romney would argue that ideology and interest, not sentiment, cause any given country to object to the leading world power. Attempting to appease sentiment would thus divert U.S. policy from a realistic course.
Campaign Rhetoric vs. Reality
I have tried to flesh out the kinds of argument each would make if they were not caught in a political campaign, where their goal is not setting out a coherent foreign policy but simply embarrassing the other and winning votes. While nothing suggests this is an ineffective course for a presidential candidate, it forces us to look for actions and hints to determine their actual positions. Based on such actions and hints, I would argue that their disagreement on foreign policy boils down to relying on regional balances versus active balancing.
