The USA can not tolerate a nuclear Iran. And, Israel will not...using whatever means is necessary to stop the threat.

Probably yes.
Is the USA? Probably no.
According to James Risen of The NYT, the Iranians have the warhead design thanks to Clinton and Operation Merlin. Their current Shahab missiles have the range to cover all of the Middle East and parts of southern Europe and Asia. Seems like all they need now is the weapons grade nuclear material.
I was going to say the same thing. There is a long road from having the material to controlled fusion. Of course...they could already have the means in place and just need the core...don't know.
