At no time should OUR military equipment building be OUT SOURCED to another government.
This should be the Number one Rule when it comes to the DOD. There is no excuse for outsourcing any of our military equipment ever.
I'm reminded of a scandal that arose, some decades ago, when the Navy outsourced the production of a strategically-sensitive milling machine to Toshiba. This machine was used to make propellers for submarines, and it was one area where we had a very significant advantage over the Soviets; that we were able to make better submarine propellers that allowed our submarines to be quieter and more stealthy.
Toshiba made one more of these machines than we had contracte them to make, and sold it to the Soviets. A short time later, the Soviets were making propellers for their submarines that were as good as the ones we had for ours, and we lost an important advantage.
