Maybe the only possible bit of credit we can give the guy is he said no when the Israelis wanted to use theirs.

Isn't it after all supposedly the world's worst kept secret that they have some too ?

But I'm also kind of concerned what happens in the unlikely event he does well in the mid-terms, and the same after the Israeli elections ....

The more likely hyperbolic step would be to blow up outgoing pipelines and apply secondary sanctions. Or, as threatened, blow up power and water treatment plants killing large swaths of the civilian population. Nukes wouldn't be necessary to cause mass death.
