Unofficially, Israel has over 200 nukes, so no attack on Israel will be forthcoming.
On the other hand, closing the Strait of Hormuz IS something they've been training for since...well...almost forever.
They don't even have to succeed or succeed long term, because any shutdown in the Strait will cause oil speculators to lose their sh*t and get hysterical.
Robert Rapier, an energy expert for Forbes, 60 Minutes, and God knows how many other shows and publications, said in 2012 that any Iranian closure of the Strait would likely result in $200 a barrel oil.
And that was six years ago.
You can bet it would be closer to 250 or 300 a barrel today, and that would translate roughly to between $7.00 and $9.00 a gallon for Regular Unleaded gasoline.
