Without boots on the ground, relying on air power and 'moderate rebels' you are looking at at least a decade of war (using Syria and Libya as best-case-scenarios examples; Assad regime was nothing like the Iranian). The Israelis are dividing the opposition by pushing the out-of-touch monarchists as their would-be puppets and the Trump regime are backing them too. Which means they are not even seriously pushing any viable or credible alternative. They are likely arming the Kurdish and other ethnic factions in the region and stoking ethnic conflict. It is in Israel's interests to prolong the conflict , to degrade Iran's military and economy (like they did in Syria) and even break it up into smaller manageable parts. The monarchists are a moon-shot; Reza Pehlavi is not his father (who also was a US puppet) - Israelis like him because he will be weak and pliable and completely dependent on foreign patronage.
Interesting point on Israel pushing for the monarchy to come back.
Democracy in the middle-east does not result in Israel or US aligned governments, but the monarchies have proven more interested in preserving their autocratic dynasties and quite easy and eager to work with Israel and the US to preserve themselves.
