Israel knows that it cannot count on our Hussein for assistance. He will criticize any attack on Iran. And should Iran launch terror operations against the US, here or abroad, Hussein will excuse them as necessary/reasonable or God knows what, laying the blame squarely on Israel.
Israel doesn’t need Hussein’s assistance, nor does his criticism matter. The rest of the world has taken his measure and they see Jimmy Carter.
Israel will go strong. It’s going to be a coordinated attack with ballistic missiles and fighter/bombers and special ops. To reduce Iranian responses re: the Straits of Hormuz, they will also take out a significant chunk of Iran’s navy. Then they will hunker down and let Obama and others criticize them (while all in the West will be secretly thanking them).
The most pressing question is whether Obama will take action if Iran tries to block the Straits of Hormuz. He won’t want to, but he has no choice.
