He's now openly arguing Iran should have them because other countries do. This is the same guy who spent four years threatening "fire and fury" over Iran's nuclear program and killed Soleimani over escalation fears. His entire Iran policy has collapsed into pure improvisation. First he's signing deals, now he's handing out legitimacy to Iranian weapons development. This isn't chess, it's dementia-coded foreign policy where yesterday's enemy becomes today's conversation partner because he's bored or got a different briefing.
