US Envoy to the UN Mike Waltz on the possibility of escalation: The president is keeping all options on the table. What the president is doing right now, as we've seen all along, is giving some talks some space. Talks are ongoing. They're happening at every level. What we are constantly seeing, though, is that on the Iranian regime side, they are divided. There is internal fighting. Some are seeking the guidance of the Supreme Leader. Others want to move in a different direction. That makes it hugely challenging from a diplomatic standpoint, but to get to some reasonable resolution here.
