Iran has been accelerating its breaches of the nuclear deal and earlier this month started pressing ahead with plans to enrich uranium to 20% fissile strength at its underground Fordow nuclear plant. That is the level Tehran achieved before striking the deal with world powers to contain its disputed nuclear ambitions.

The Islamic Republic’s breaches of the nuclear agreement since President Donald Trump withdrew the United States from it in 2018 and subsequently imposed sanctions on Tehran may complicate efforts by President-elect Joe Biden, who takes office on Jan. 20, to rejoin the pact.

“The Trump administration chose what it called the maximum pressure campaign on Iran. The result was that this strategy only increased the risk and the threat,” Le Drian told the Journal du Dimanche newspaper.
