The US will focus on this issue instead of restarting the Iran nuclear deal.

The United States of America will focus on disrupting the supply of weapons from Iran to Russia , which the aggressor will use in the war against Ukraine, and not on restoring the nuclear deal.
According to Bloomberg , the US Special Envoy for Iran, Robert Malley, noted that Tehran does not yet seek to restore the nuclear deal.
“Right now, we can make a difference by trying to contain and disrupt the supply of weapons to Russia and by trying to support the fundamental aspirations of the Iranian people,” Malli said.
The publication notes that Iran is increasing uranium enrichment activities and limiting international monitoring. Last month, at an IAEA meeting, the country was condemned for obstructing the investigation of uranium particles found at several undeclared sites. In addition, Iran has demanded an end to the IAEA investigation as part of any renewal of the nuclear deal, a condition rejected by the US and its allies.
Although negotiations with Iran were not officially abandoned, in fact they have been frozen since the end of August. Therefore, the United States is interested in focusing all its forces on disrupting potential arms deliveries from Iran to Russia.
Malli added that if Iran sends ballistic missiles to Russia or helps build weapons production facilities, it will mean Iran has “crossed another line.”

“Right now, we can make a difference by trying to contain and disrupt the supply of weapons to Russia and by trying to support the fundamental aspirations of the Iranian people,”
The Biden administration could give Ukraine long-range missiles, more air defense systems, a few planes, a few tanks and permission to strike mafia soil. That would be much more effective than trying to stop deliveries from one shithole to the other, which won’t work anyway.
Possibly, although I still contend that moskovia must be completely isolated from the rest of the World so that nothing can enter or leave except via very expensive means.
