Klare Worte über die US-amerikanische Iranpolitik findet Richard Kemp in einem Kommentar für Ynet:

The White House knows that no diplomatic understanding with Tehran is worth the paper it’s printed on and no such undertakings will stop Iran from becoming a nuclear-armed state.

So why are they heading down this path? There are two reasons. The first is to give Biden a win on the international stage that he so badly needs after the debacles over withdrawal from Afghanistan, the Russian invasion of Ukraine and China supplanting the U.S. as power broker in the Middle East.

The second is to pile pressure on Israel and this again has two parts. Part one is to deter Jerusalem from executing a major military strike against Iran’s nuclear programme which has become more plausible since Benjamin Netanyahu resumed the premiership.

Despite the catalogue of foreign policy failures that arose directly from craven weakness in Washington, the White House does not seem to have learned that deterrence is the most effective means of averting war and remains fearful not only of wielding a credible military threat against Iran but also of Israel doing so. Biden and those around him know that an extant nuclear agreement with Tehran, supported by the Europeans, complicates any military action by Israel. (...)

If Biden’s non-deal materialises it will represent another catastrophic foreign policy failure that will have repercussions well beyond the Middle East. It will be supported by European governments and will reinforce the perception, and the reality, of Western weakness that encouraged Putin to invade Ukraine last year. What we’re talking about here is pure appeasement and empowerment of a regime that is implacably and actively opposed to the U.S. and everything it stands for.

Tehran has become the main weapons supplier to Russia, providing thousands of killer drones that have been used to aid and abet war crimes against Ukrainian civilians. Aside from the drones’ criminal use, even their export by Iran is currently illegal under the terms of the UN Security Council resolution that supported the JCPOA nuclear deal. That restriction is due to expire in a matter of months, along with UN restrictions on Iran’s ballistic missile programme.

The mood of appeasement in Washington and European capitals suggests no attempt will be made to extend or replace it. Failure to clamp down effectively against Iran’s support for Putin’s war, so obviously to help bring about Biden’s deal, also increases the flow of traffic in the opposite direction, with Russia already providing significant funds to Iran and considering the supply of combat planes and missile technology.
