The clerical regime in Iran is involved in a number of foreign adventures, the nearest to us in Syria and Lebanon. This imperialist program has impoverished the hundred million strong Iranian population, and they are starting to protest. It is a natural reaction (see below how fatigue works). According the last night's news, the faceless rebels have tried to take over police stations and there is some armed resistance. I do not know if the rebellion can achieve traction and momentum. It will surely cause stress within the Iranian leadership and bring on personal changes.
Trump verbally encourages the rebels but that is all. I would not put my faith in American assurances. Europe is totally silent, it is a continent frozen in fear of a new wave of political refugees. Israel has nothing to do with Iran's or any other country's internal affairs. We learned in Lebanon that interventions turn against us, they create enemies where there were none before.
