As the Trump administration draws up war plans against Iran over what it says are threats to American troops and interests, a senior British military official told reporters at the Pentagon on Tuesday that he saw no increased risk from Iran or allied militias in Iraq or Syria.

A few hours later, the United States Central Command issued an unusual rebuke: The remarks from the British official — Maj. Gen. Chris Ghika, who is also the deputy commander of the American-led coalition fighting the Islamic State — run “counter to the identified credible threats available to intelligence from U.S. and allies regarding Iranian-backed forces in the region.”
