We're uniquely suited to not support the F-35. Not unless you swap out the engine for a Safran one, change the avionics for Dassault's, rip out the rest of the electronics for the Thalès stuff and replace the ordnance with MBDA's.
We'd keep the frame, but Serge Dassault and Charles de Gaulle would probably smite any French mechanic coming within 20 feet of a F-35 to do anything but dismantle one for its secrets.
