The alleged Iranian-linked terror plot at a British air base is falling apart, which is bad news for officials who hyped it and good news for skeptics of the case against Iran.

• All five men arrested near RAF Fairford have been released on bail, and no working explosives were found in their vans.
• Under UK law, real terror suspects can be held for two weeks, so bail suggests the charges are ordinary crime, not terrorism.
• A leading theory: they were stealing red farm diesel, a theft wave up sharply since diesel prices jumped after the war with Iran.
• Trump and Marco Rubio keep calling it a serious foreign-actor plot but have never once said the word "Iran."
• The farmer who spotted the men says she saw 8 to 10 of them, and no official has ever contacted her.

Outlook: Expect the story to quietly fade unless authorities produce actual evidence tying the men to a foreign state.
