Charles Krauthammer says to keep the pressure on Iran:

One can never be sure how these double- and triple-agent mirror games are played, which might be why the NIE is only “moderately confident” it has gotten this one right.

Assuming it has, the conclusion drawn by some–that this means Iran has abandoned its nuclear ambitions–is not just wrong but also contradicted by the NIE itself. Suspension does not mean abandonment. The program can be restarted at any time. The fact that huge amounts are still being spent on uranium enrichment and missile development–the other essentials for a nuclear-weapons program–while the weaponization part remains dormant is overwhelming evidence of a country that wants to go nuclear but is being restrained by international pressure.

Which is why the critics’ claim that this NIE report is a mandate for a new and soft Iranian policy is wrong.
