Just couldn't wait for diplomacy to play out.
IIRC, Iran appeared to comply with the terms of the agreement and once that was out of the window they no longer complied.
Perhaps we should be making the argument that Trump shouldn’t have only gonna off of Israeli intel, but he ended up being correct that Iran wasn’t correctly reporting their enrichment stockpile, which was a provision of JCPOA. The reason why JCPOA wasn’t revived is actually because of Iran refusing to cooperate about what they did with the undeclared nuclear material.

If they hid things and the agreement wasn't just trashed, that could have been a scandal that gets resolved on the path to peace. It could happen for many reasons, maybe they don't trust the West to uphold their part and wanted an insurance policy, maybe it was division within. It doesn't matter that much, it's not like they made the bomb already and were about to hit once everyone lowers their guard.
Later what we had was Iran that was on the table, trying to play nice and that was destroyed probably because of the ego of a guy who couldn't handle to stick with the agreement signed by someone he hates.
Unfortunately the American attitudes will result in proliferation. Not the Iranian ones.
Now we know the timeline where agreements are not honored by the US.
> Who knows how things play out when a country is integrated back in the international system and have something to lose when if get caught on checks
Ah that's the Merkel's school of international relations =) We also know that with a russia example which you mentioned. Didn't work too well, did it?
Btw, DPRK were also given many concessions and reintegration opportunities (Kaesong) yet that was not the path they chose.
Who knows, it's all speculation at this point. The current reality is that if you don't have a nuke you get invaded. Everyone will have nuke soon. Those who fail will be destroyed because agreements, international laws etc doesn't mean anything anymore.
