F-35 Cancelled, then what ?

My opinion is, I'm as clueless on the classified performance as most of the posters here.

However, just two pages ago, UK Beck said.
“This jet isn’t just about the weapons — it’s a game-changing capability. The Tornado GR.4 can't just stroll into a double digit SAM MEZ [Missile Engagement Zone]. In the F-35 I can generate a wormhole in the airspace and lead everyone through it. There isn’t another platform around that can do that. This isn’t all about height and supercruise speed — it’s the ability to not be seen,” added Beck. “We can never be explicit about the true capabilities of this jet, we've got to hold our cards close because otherwise people will try to reverse engineer it. This aircraft is so sophisticated that no pilot who has actually flown it says a bad thing about it. That tells you a lot about what this can do.”
