Will US Policy on Iran Change After Election? Henry Ridgwell LONDON - Since his election in 2016, U.S. President Donald Trump has withdrawn from the Iran nuclear agreement signed in 2015 by his predecessor, Barack Obama, and imposed tough sanctions that have crippled the Iranian economy. How might the relationship between Washington and Tehran change after the U.S. election on November 3? 2020 began with the United States and Iran on the verge of war. The U.S. targeted killing of revered Iranian General Qassem Soleimani January 3 - whom Washington accused of masterminding numerous attacks in the region - sparked fury in Tehran. It retaliated with missile strikes on U.S. bases in Iraq. No U.S. service personnel were killed and conflict was averted, but Trump kept up the pressure. "The United States will immediately impose additional punishing economic sanctions on the Iranian regime," Trump told a press conference January 8, the day after the Iranian missile strikes. .
