“Every pilot who has flown it, praises it.”
Every pilot had better, politically speaking.
You are wrong about that and overestimating the ability of America to influence other countries. In Europe the political pressure is to have Eurofighter Typhoons and the ones wanting F-35s are the actual pilots and generals. German air-force chief was just fired because he liked F-35 for their coming Tornado replacement, but the politicians prefer Eurofighter.
