Bravo Two Zero was the longest escape and evasion in SAS history, hence why it's famous. If a Yank detachment had done the same thing.....don'tcha think it'd have been national news at some point? I challenge you to find any record whatsoever of a US unit tabbing to Syria during Desert Storm.
In any case, the only reason B20 had to tab to Syria was cos the numpty in charge of comms had the wrong frequency, if they'd been able to call in they'd have had a helicopter pick up. Ask your mate why they didn't get a pick up and chose to walk out.
