WorldWhy did the Pentagon rush to pull all its B-1 bombers from a British airbase?

Secretary of State Marco Rubio called the move a routine redeployment, while President Trump said it was prompted by a threat. The decision came a week after five men were arrested near the base on suspicion of preparing a terrorist attack, followed by the arrest of a British-Iranian dual national. All six have since been released on bail, and Iran strongly denies involvement.
