Iran-US relations might witness a turnaround. The main challenge for the Biden administration will be to recreate trust in the Iranian government. The Trump administration’s withdrawal from the deal has left a deep sense of mistrust which is likely to persist given the lack of guarantees that a new deal would be sustained. However, there is a symbolic value in the US’s return to the JCPoA as it counts as an admission that withdrawing from the agreement was a mistake.
In the US, despite the growing politicisation of the JCPoA issue, there is unity among the democrats in supporting diplomacy.
