@kentwillard i think it fair to say Biden has both national-interest and political incentives in the mix. it’s been rough on his domestic coalition, but as you say he can still hope for Saudi Arabia’s vote at the pump this November. i think the US is already pretty clear that it sees Hezbollah, Hamas, the Houthis, and some less well known groups in Syria and Iraq as ultimately answering to Iran (and indeed Iran describes them as its “axis of resistance “).
