The US war with Iran is going badly, and Trump is now threatening an ally that has been helping broker peace — a bad sign for anyone hoping the conflict ends soon.

• Trump said the US will bomb Oman if it "gets in the way" of talks over control of the Strait of Hormuz.
• Oman is the main go-between with Iran, so threatening it makes a deal harder, not easier.
• The war's goals have shrunk from regime change and stopping Iran's nuclear program to just reopening the Strait — and the US may not be able to do even that.
• American missile and air-defense stockpiles are running low after years of arming other wars, including Ukraine.
• Marjorie Taylor Greene says tactical nuclear weapons against Iran are being discussed inside the government, a claim that has drawn almost no pushback from Democrats or major media.

Outlook: With a naval blockade grinding on and no diplomatic path, expect more escalation and pressure on oil shipping through the Strait of Hormuz.
