One suspects some heated arguments are happening in Washington

Two stories at Axios.  First:

The U.S. and Israel have discussed sending special forces into Iran to secure its stockpile of highly enriched uranium at a later stage of the war, according to four sources with knowledge of the discussions.

Why it matters: Preventing Iran from ever obtaining a nuclear weapon is one of President Trump's stated war objectives. The regime's 450 kilograms of 60%-enriched uranium — convertible to weapons grade within weeks — is one key to that goal.

The big picture: Any operation to seize the material would likely require U.S. or Israeli troops on Iranian soil, navigating heavily fortified underground facilities in the middle of a war.

• It remains unclear whether it would be an American, Israeli or joint mission.
• It would likely only take place after both countries are confident Iran's military can no longer mount a serious threat to the forces involved.

Behind the scenes: At a congressional briefing Tuesday, Secretary of State Marco Rubio was asked whether Iran's enriched uranium would be secured. "People are going to have to go and get it," he said, without specifying who.

 Hard to imagine that going all that smoothly!

The other story:

Israel's strikes on 30 Iranian fuel depots Saturday went far beyond what the U.S. expected when Israel notified it in advance, sparking the first significant disagreement between the allies since the war began eight days ago, according to a U.S. official, Israeli official and a source with knowledge.

Why it matters: The U.S. is concerned Israeli strikes on infrastructure that serves ordinary Iranians could backfire strategically, rallying Iranian society to support the regime and driving up oil prices.

It would seem there's a good chance that Trump feels a bit trapped - he presumably doesn't want to be blamed for rising oil prices and Americans in danger in the Middle East, and may be legitimately wary of being able to "sell" to his base the need for boots on the ground in Iran.   However, he has Netanyahu to try to keep happy, too.
