I'm perfectly happy to screw Boeing as hard and as many times as we wish. As I say above, our armed forces sometimes appear to be sponsored by them
The perceived embarrassment is that we chose to:
1) Order the things in the first place
2) Made a decision to defer our order to save money (when has that ever worked??)
3) Find that the cost has increased by £0.5bn
4) Suffer (contracted) buyers remorse
5) Try to cancel without going through the proper channels
6) Have the entire process reported on in the press
Somewhere between 3 and 5 we had a Defence Command paper.
As for Biden, he's got bigger issues than the emotional state of a rapidly declining and unreliable ally, that keeps gaping military capability. Irrespective if he's fit to be President.
