Waiting for Shahab

Remember that NIE that said that Iran wasn't pursuing nuclear weapons?

I was reading The Corner at National Review this morning, and saw a post by Jonah Goldberg linking to an article in the London Times here.

Why would Iran be developing a ballistic missile capability to hit Europe if it wasn't to mount a nuclear warhead? I would guess that this generation of missile probably has a CEP around 1000m or so, way to inaccurate for conventional warheads. I also can't say if mounting a chemical or biological warhead on one of these would make sense either.

Plus, the Iranians continue to enrich Uranium, and are expanding their capability.
