I would suggest that the ill advised transfer of British jet technology 60 years ago is hardly comparable to the continuing sale (or presentation given the Israelis get much of it at no cost) of high technology to a nation with a recent track record of reverse engineering and sale to China and/or the highest bidder.
The J-10, Chinese/Israeli Phalcon AEW Project, and US radar and weapons technology sold by the Israelis to South Africa, Chile, Ecuador, Sri Lanka and various other nations are the principle examples, some of which have already been mentioned.
