So us has been funding the death of iran 40 years ago, and iran has no right to say anything about it? This is far more than supporting terrorism. This is supporting your neighboring country to attack you.
Rest of your arguments are irrelavant. Biggest ally of us is saudis, and they are doing pretty much everything iran does, in a highly totaliter regime. They kill opponent, hang homosexuals, have a supreme regime, yet us loves them.
I am just saying, there is bit of an inconsistency here.
