In reply to Saor Alba:
i think the main UK componant in the F-16 is the Ejection seat. we don't, from recall, sell them anything 'kenetic' because we don't produce anything kinetic that they either want to buy, or that they can't buy something similar for peanuts from the US.
if we won't sell to them, they may not sell to us - and we are heavily reliant on their optic/designation systems and UAV's, and they produce the best that can be bought.
personally, i can live with the trade - not only would us throwing our toys out of the pram achieve very little for Palestinians, but it would harm us significantly, both through not being able to use their kit, and the fuss it would cause with the US.
appalling as it may be, i value UK lives and interests over Palestinian ones, or Israeli ones, or American ones. if its in UK interests for Palestinians, or anyone else, to get the shitty end of the stick, then i can live with that. its not nice, and if i could bring peace to all while maintaining UK security, i would - but i'm not going to risk serious harm to UK interests for other people.
