The point isn't that we should take overt military action against Iran. This would not be a good idea at this time.

The point is that the Golden Standard of liberal foreign policy: endless negotiations, inspections and warnings from international nuclear regulators, and months of speeches and handwringing in the U.N., isn't doing squat either.

My own personal thinking is that more should be done to encourage moderate groups and citizens in Iran (and there are actually quite a few) financially and otherwise, pressuring their government from within. At least that should be the first step.
