Also, like it or not the Saudi government is supported by the UK and US. Any of our pilots out in Saudi are supported and sanctioned by the UK. We are not likely to go to war with Saudi. The biggest point for me though is not at a government level. When you qualify as a Fast Jet pilot you join a club, to my mind that club includes the USA. If you subsequently go and train Chinese pilots (the clear enemy of one of our closest allies) you are betraying your mates.
