Iran is vehemently against war and WMDs, and killing of innocent civilians, even Israeli civilians.
They will not be the ones to escalate this . They don’t want to. But in a fight Iran vs Israel-even if Israel uses nukes- Iran will win. Their mass land compared to Israel’s like a postage stamp is one of the reasons. Iran has superior weapons. They are in Russia producing weapons for them!!
Israel knows this and the U.S. knows this. That is why Israel’s latest strike was to save face only. Iran can easily flatten Israel.
