Matthias Küntzel is a German political scientist with a focus on the Middle East. He provides astute analyses of the German and more broadly the European role in responding to the challenges posed by the Iranian regime; two of his books are available in English from Telos Press. His current piece, published here, sheds important light on the challenge of the moment: the Biden administration’s vocal commitment to returning to the JCPOA—a long-standing position during the presidential campaign—but facing continued intransigence from Tehran, willing to accelerate its nuclear program, indeed all the more so in the wake of the Biden election. Once it became clear that Trump and Pompeo were on their way out and that the incoming administration, which had been advertising its support for the Obama-era deal, would take over, Tehran became more, not less, aggressive on the nuclear front. It is presumably calculating that increased pressure will lead Washington to buckle by lifting sanctions first, in a way that would certainly not have succeeded with the previous administration. That makes the moment all the more fragile and fraught. Küntzel leads us through this maze.
