I read Scott Aaronson's blog posts this week and he makes a seemingly similar argument, behind his tendency for heated rhetoric.

If the international community will barely lift a finger to resolve the I/P issue, then it is predictable and rational for Israel to take matters in their own hands and use violence (implemented as a "preemptive war") to "solve" their national security threat problem. It's a type of political realism argument to support this outcome. No appeal to a country being enlightened or democratic, etc., will work.
