Israel, which is a U.S. client state, is granted a right similar to that of the United States. The United States owns the world and can do anything, and its client states can be regional hegemons. Israel wants to make sure that it dominates the region and therefore can carry out whatever policies it wants to in the occupied territories, invading Lebanon or whatever it happens to be. The one threat that they cannot overcome on their own is Iran.
Israel and Iran had pretty good relations right through the 1980s. They were clandestine relations but not bad. And now they recognize that Iran is the one barrier to their complete domination of the region. So therefore they want the United States, the big boy, to step in and take care of it and if the United States won't, they claim they'll do it. I don't think they would unless the United States authorized it. It's much too dangerous. They would do it only if they're pretty sure they can bring the United States in.

"I don't think they would unless the United States authorized it." That's wrong.
Israel doesn't take marching orders from the U.S. The Jewish community in the U.S. has way too much money and control in key sectors of the economy and can and does buy too many politicians to allow the U.S. to tell Israel what to do. They also have key people in other major countries around the world. Wake up.
