The Biden administration now admits a nuclear deal with Iran may not happen despite its continued outreach to Tehran. There are signs the administration wants to pin the blame on former U.S. President Donald Trump, whose withdrawal from the original nuclear deal supposedly provided Iran with the pretext to advance its nuclear weapons capabilities. But the uncomfortable truth is Iran’s most aggressive moves came after U.S. President Joe Biden was elected. What’s driving Tehran forward is not Trump’s maximum pressure campaign but Biden’s decision to ease that pressure. Simply put: Iran is doing what it can get away with.
