Too bad the US won't sell it to anyone else.
The F-35 was supposed to be the fighter that the US and her allies could all buy without the US having to sacrifice performance edge by selling F-22s. Moreover it was supposed to be economical because so many nations would buy in. But the jet was made so complex and there have been so many problems getting it to work that costs have skyrocketed, nullifying one of the main original goals of the program (affordability). Instead if has become a horrifically expensive corporate welfare program.
