Iran threatens to attack the U.S. if it assists Israel in defending against any Damascus retaliation.

On Monday night, Iran conveyed to the Biden administration that if it involved itself in defending Israel were Tehran to undertake a retaliatory strike, it would consider the United States a viable target as well. The issue was discussed at a Tuesday NSC meeting, according to notes reviewed by The Intercept. (The NSC did not respond to a request for comment.)

Since then, the U.S. has quietly conducted talks with Iranian officials to seek to avoid direct confrontation between the two countries’ armed forces, according to CNN and other media reports. On Sunday, Senate Majority Leader Chuck Schumer said that Biden and his team are working to prevent escalation with Iran in the Middle East.
