There is no deal. The problem with Iran is that it's a regional power that is not aligned with Israel, so Israel has been insisting for decades that it must be attacked. The desired outcome of course is not to "free" Iran but to weaken it so that it can't be a rival power. So first it claimed it was because of Iran's nuclear program, and when Obama put that under control with an agreement that gave Iran the opportunity to thrive, it pushed Trump to renege the deal so Iran's nuclear could be a problem again and the sanctions restored.

It's a regional power that funds militias and paramilitaries in half the middle east, which uses those paramilitary organizations to exert control and influence over their neighbors and occasionally to assassinate political opposition (e.g. in Lebanon, Iraq), and to prop up the likes of Assad (Hezbollah got involved in the civil war on the Assad side, and in one instance laid siege to and starved out a village) and threaten Iraq, Egypt, Saudi Arabia, etc.

Israel is part of the equation but Middle Eastern politics is more complex than that.

It's a power whose slogan is "Death to the US" and which has been doggedly working on nuclear weapons for decades. Try and temper the Israel Derangement Syndrome sufficiently to see that the US and the Mideast would be better off without the Iranian theocracy.
