The Israelis hacked their street TV cameras to see everything going on there to know just who was where when, so I'm guessing that Israel has fantastic intelligence on Iran while the USA has the might to exploit it.
Consider how this war has gone then consider that while Iran has been free to lash out at the world unrestrained, we (and Israel for the most part) have highly constrained themselves to only targeting known military targets avoiding civilian casualties to the best of our abilities.
If the USA went all out with no regard for consequences, we could do far greater damage in far less time at far lower cost.
