there is no reason for US to enter into this interdependency when it could use F-22 supply chain to modernize both F-22 and create F-35. This Eurofighter and Rafale are kept afloat by exports to Mideast.Trump evidently doesn't appreciate that the whole point of making JSF an international program with globalised production arrangements was to suffocate alternative development and procurement programs, fattening the profits of Lockheed Martin and ultimately giving Trump the power to ground the Danish Air Force on a whim.
If all F-35 components were produced in the United States, then parallel production of those components outside the United States for non-US customers would no longer be economically viable, which would in turn lead partner nations with the requisite engineering expertise (or ambition to develop it) to seek alternative procurement and development pathways that better support their own strategic-industrial objectives, undermining the profits of Lockheed Martin and eventually creating competing platforms that Washington does not control. Indeed, we have already seen how Turkey's ejection from the F-35 program turbocharged that nation's own aerospace ambitions. That F-35 partner nations do not have sovereign control over their aircraft also appears to be one of the major drivers behind the UK and Japanese commitment to GCAP.
Germany and Poland that were not part of original F-35 team bought it anyway. Turkey has to buy F-16 for the price of F-35 with much delayed delivery dates. If somehow this GCAP is created than some new dependencies highly likely emerge even they not buy into it. the sooner Europe and Turkey realize that they shouldn't pursue such projects the better for them.
