People with big egos often throw tantrums, US and other presidents are no exceptions. And you need a big ego and some other nasty personality traits to navigate super-competitive realm of high politics and end up with some powerful role. Iran treatment after islamic revolution and temporary imprisonement of diplomats and CIA officials can be described as bruised ego / tantrum from outsiders perspective. There were great relations before and could have been good relations after if US was willing to put a blind eye on that (like it does with neighboring Saudi Arabia and all that is happening there).
