Just sanction the Iranians for attacking the US embassy in Iraq. Yes for people who don't know attacking an embassy is an act of war, and warrants a response because if we let Iran attack one embassy China or Russia will do more sonic-based sound attacks on say the Cuban Embassy, and that could kill the US ending the Cuban embargo.
Edit: This was unexpected but not surprising. Biden is to the right of Obama on foreign policy was expected, but I assumed he would go back to the Iran deal, but I suspect he doesn't care if the Iranians get the bomb as long as they are too weak to enact their Shia regional dominance across the region. I mean the EU sanctions Russia despite the fact that they could nuke the EU.
By the way for those who just focus on Saudi Arabia badly, Iran is pretty bad too, but I suspect the progressive groupthink of the friend of my enemy bullshit logic won't accept that, but they don't threaten the International system like Russian nukes, or China does.
Edit 2: For those who disagree with me, if you want the US out of the Middle East with no embassies you should have voted for Bernie instead of shill for Biden, and not put pressure on him.
