Two men have been rearrested in Britain on suspicion of assisting Iran's intelligence service in a plot targeting a U.S.-run air base — a direct consequence of Washington's foreign entanglements arriving at the doorstep of American military assets.

RAF Fairford in western England, used by the U.S. to bomb Iran during this year's war, was the target of a suspected terror plot on September 27. Armed police and army bomb-disposal units swarmed the rural area. Scores of residents were evacuated from their homes. Authorities found gasoline — an accelerant — in three vans at the site, but no explosives. The U.S. responded by pulling its bombers from the base.

Counter Terrorism Policing said Tuesday the two suspects — a 24-year-old British national and a 25-year-old dual U.K.-Iranian national — were rearrested under the National Security Act after initially being detained in late September and early October and then released on bail. Five other men arrested earlier also remain on bail. No one has been charged.

Laurence Taylor, head of National Counter Terrorism Policing in the U.K., said investigators consider it "highly likely that there is Iranian state involvement" and are still examining "what that level of involvement was and the ambition behind it." Breitbart reported that Prime Minister Andy Burnham went further, calling the plot "almost certainly" directed by Iran's Revolutionary Guard.

Iran has denied involvement. But the regime has also made clear that any base used to attack its territory is a legitimate target. The Iranian Embassy in London, as CBS reported, "categorically rejects and strongly condemns" the allegations — a carefully worded diplomatic denial that stops short of disavowing the threat.

This is not an isolated incident. MI5 head Ken McCallum warned last week that both Iran and Russia are expanding attacks inside Britain, with Tehran moving beyond its traditional targets of Iranian dissidents toward Western assets. More than 50 people have been arrested over Iran-linked plots in the past year, according to Breitbart's reporting.

The pattern is plain: Washington bombs Iran from British soil; Iran hits back at the bases hosting those bombers. The establishment calls it aggression; the rest of us should call it predictable. Meanwhile, the southern border stays wide open, and the same policymakers who dragged the U.S. into another Middle Eastern conflict insist the only answer is more involvement, more spending, more projection of power abroad while the homeland remains undefended.

The question isn't whether Iran will keep testing U.S. assets — it's how long Americans will tolerate paying for a foreign war that follows their military home.
