No, they are not. Both Hamas (that Israel help created, remember?) and Hizbollah have elected representatives, and both care for their populations, to whom they also offer social services. Once you are elected, you are no longer a terrorist - you may support it but what you do isn't terrorism - it is foreign policy. The same happen to pre-1948 jewish terror groups that became Israel's government. I don't remember an act of terror by Iran, other than empty zionist accusations as thin as cigarette paper. Sure, they are arming the resistance in the Arabic peninsula, but it isn't terror. Terror is what happened in Paris, London etc, by ISIL, that Israel props up like they did for Hamas. In this sense, Israel is a lot more of a terror nation than Iran - and they already have nukes, having signed no anti-proliferation treaty about them neither. And that's not counting the chaos they sow everywhere around them, creating causes for terror. The Sauds, too.
