Trump launches US-Israel war against Iran to stop a nuclear program his own 2018 withdrawal made possible.
The deal was not perfect. Its critics — including many who supported withdrawal — pointed out that it had a 15-year sunset clause, that it didn't address Iran's ballistic missile program, and that it didn't constrain Iran's regional proxy activities. These are legitimate criticisms. The question is: what did withdrawal accomplish? The answer is documented in the IAEA's quarterly reports. Before the deal, Iran had 19,000 centrifuges and was enriching to 20%. The deal got that down to 5,060 centrifuges enriching to 3.67%. After Trump's withdrawal, Iran responded by violating the caps incrementally, then rapidly. Each step was Iran's response to the US tearing up the deal and reimposing sanctions without getting anything in return.
The European allies — UK, France, Germany — stayed in the deal after Trump withdrew and pleaded with the US to return. The Biden administration attempted to rejoin in 2021 but negotiations collapsed before a deal was reached. Iran used the years between Trump's withdrawal and any potential return to dramatically advance its nuclear capabilities. The "maximum pressure" campaign Trump launched produced no concessions from Iran — it produced a more advanced nuclear program and a regime that concluded it was better off enriching uranium than negotiating with an American president who walked away from signed agreements.
