The parallels between the TSR.2 and the Arrow are remarkable. I seem to recall stories about Israel and Japan also developing leading-edge fighter aircraft, but being pressured to buy American, so that the Western-bloc countries would have "compatible" equipment. In the cases of Canada and Britain, it seems that the governments weren't clearly focused on the goal, and the Americans saw the marketing opportunity. Just my impression, so any comments or opinions are welcome.
