The Brits can send all they want. In fact this brave soul should strap himself in and go himself. But he won’t. They never do. If he didn’t have America standing behind him, he’d be selling shoes in Macy’s.
Britain doesn’t have F-16’s
They are talking mainly of Dutch F-16’s, currently surplus, and IIRC many of these are already in storage in Belgium, as the Netherlands is converting to F-35s. Norway and Denmark are divesting F-16s too.
The talk is of conversion training in Romania, which also operates F-16s.
BINGO!
