The saber-rattling is compelling no doubt, but:
There is
NO WAY IN THE WORLD that Iran, if they actually developed a NUKE, would use said NUKE on Israel. They would be committing literal suicide.
It's great for the Khomeini's to stir up public sentiment against the west:
It makes great TV, it grabs headlines, and it stirs the 'base' (sound familiar?)
BUT:
If Iran got their own NUKE, and used it against Israel, the western world
WOULD WIPE IRAN OFF THE MAP... (I'm pretty sure China and Russia might even help, or at least let us use their air-space).
(
The global community is simply not going to tolerate these Nagasaki/Hiroshima-type situations in 2012).
