Why Obama Won't Bomb Iran
Why Obama won't bomb Iran
Here's why I don't think it's probable absent some dramatic development: there would be very little international support for the effort. If the lead-up to the Libyan intervention is instructive, it should tell us that the administration values multilateral cover - in the form of a UN Security Council resolutions and the sanction of the Arab League. It is difficult, at least today, to see either of those bodies signing onto a military campaign against Iran. Russia and China are likely to shield Iran in the Security Council and the Arab League is still smarting over Libya.
So yes, as David Rothkopf writes, the administration is not shy about using force, but it has only undertaken large-scale action against another state when the multilateral stars aligned. Picking off the odd pirate and terrorist via drones doesn't really approach the magnitude of starting a major war with Iran.
