There's no sovereignty issue. Where your pilots are trained makes no difference, unless you believe that the F-35 will remain operationally functional for any useful period without the active support and approval of USG.
After all it has been stated that the F-35 can't be operated effectively without a link to ALIS. And it would be foolish to discount the possibility that in a Syria-type scenario that went active, with some allies standing aside, a future administration would cut off or reduce support to the non-combatants in order to guarantee support to deployed aircraft.
You can't get everything you want at ALIS's restaurant...
