Actually, there are lots of revolutions in Europe after WWI, but keep in mind that in this case the populations were blaming their governments for starting or participating in an unnecessary war with monumental casualties. In this case, the Iran government has two useful scapegoats and any casualties could be easily ascribed to the idiots bombing girl schools and not to the idiots sending millions to their deaths under artillery fire.

While possible they could scapegoat this, hasn't the rallying cry for Iranian protests prior to this been "Neither Gaza nor Lebanon, my life for Iran" https://en.wikipedia.org/wiki/Neither_Gaza_nor_Lebanon,_My_L... - i think we are already at the place of the population blaming the government for its foreign policy consequences, at least in some segments.
