Well, they're not outright accusing the U.S., just pointing the finger of blame, which is as much an accusation. See Simon Tisdall's How Trump’s arch-hawk lured Britain into a dangerous trap to punish Iran: "With the seizure of a supertanker off Gibraltar, distracted UK government was set up by John Bolton as collateral damage."
His piece is based in part on a news report in Spain's El Pais newspaper, which cited official sources.
The British are of course complete victims in the mess, poor dears. [flipping a pen into the air]
I can't take much more of this. I'm going on vacation. Goodbye.
