Quote from tomdavis:
The F-18, despite its upgrades, is still a 30+ year-old design. The F-22 program has been stopped. The purpose of sharing the F-35 with others is to get them to share the cost.
Despite cost sharing it is still pretty damn expensive (maybe not relative to the raptor), and if we can't afford it ourselves then maybe we should put the program on hold until we can. My major gripe is sharing state of the art tech with other nations.
