I do understand why Iran (or atleast the current rulers) don't like US. But what about Israel? Do they hate it because they see it instrument of US or they hate it because of Palestine? I always though Iran acted out, to appease rest of the Muslim world. I mean most Muslims in the world are Sunni and so are countries. In some way, Iran surely feels left out or even threatened. So it tries to out Muslim Sunni dominated Muslim dominated Muslim countries. Afterall, Pakistan actually has nukes and the capability to strike Israel. What is stopping Pakistan from going Irani way? It doesn't like Israel and relationship between US and Pakistan and soured. It clearly packs more punch than Iran ever will.
