British police arrested several men on suspicion of explosives offenses near RAF Fairford, a UK air base used by American forces, forcing local evacuations and raising the question again: why are US troops still sitting targets on foreign soil?

This is what two decades of global policing looks like. American airmen stationed in Gloucestershire — there to project US power into the Middle East — now need armed roadblocks and bomb disposal teams just to sleep safely. The British can't secure the perimeter. The Americans can't leave. And the bill — in dollars and in risk — falls on the American public.

CNN reported that several men were arrested near the base, with properties evacuated in the Whelford area and the Army's specialist explosive ordnance disposal team examining vehicles. Gloucestershire police declared a "major incident" but said they believed it was "contained."

Reuters, meanwhile, reported that security at Fairford had "significantly increased" in recent days, with roadblocks, armed police, and emergency vehicles blocking access. A US Air Force spokesperson said the 501st Combat Support Wing "remains vigilant" but would not discuss specific force protection measures.

Here's what CNN didn't tell you: Iran's Revolutionary Guards warned in July that US bombers should not be allowed to fly from Fairford. Fairford, as Reuters noted, has been used to launch operations against Iran during the Middle East conflict. These aren't random arrests in a quiet English village. American forces are in the crosshairs because Washington put them there.

Britain said in July its armed forces were ready to protect the country from any attack. This weekend's police cordon and bomb disposal sweep suggest that readiness has limits.

The US Air Force spokesperson's statement — "we constantly assess a variety of factors that determine what measures we institute" — is the language of a permanent garrison state, not of a force with a defined mission and an exit plan.

No one in Washington is asking the basic question: what is the US interest that justifies keeping American service members at risk on British soil to bomb Iran? What's the cost? When do they come home?

The arrests near Fairford are contained, for now. The broader threat to American forces stationed indefinitely on foreign bases is not — and no one in power is offering a plan to end it.
