This doesn't hold water; nation-state propaganda doesn't have any effect on the funding this program receives. Nobody should have any trouble believing that an overly-ambitious pie-in-the-sky kitchen-sink project that has been in development for 30 years might be having a hard time meeting its lofty goals, or indeed nailing down its goals in the first place.
Consider the Space Shuttle program, and now realize that in four years the F-35 will have been going on longer than the shuttle program, and that the F-35 has already cost five times more than the entire shuttle program, and that the shuttle is also today considered an overall failure (and this opinion is not ascribed to "opposing forces"). And if the shuttle can be a failure while achieving more than the F-35, while costing less than the F-35, with a smaller (though still huge and confused) scope than the F-35, by what possible metric can the F-35 not be considered a failure?
