"Or even buy some from Russia"
The Russians seem to be OK with allowing other countries that have purchased their planes to produce the spare parts, so it would make sense to buy from them PAK-FAs -lovely planes, by the way- together with the permits and designs to produce every part needed locally. And we could probably buy half a dozen PAK-FAs for the cost of a single F35. And the PAK-FA avionics and electronics are simple, sturdy and don't use 'The Cloud". ;-)
The obvious downside is that by doing this, we would be supporting Putin, Steven Seagal and Gerard Depardieu! :-D
