It all stems from this: https://www.federalregister.gov/documents/2019/05/17/2019-10....

Chinese made telecommunications, EV cars, drones, or anything that can be used to provide a detailed map/surveillance of the US by China will eventually be banned.

This is a hugely important strategic move. I reluctantly concede that the federal government has done exactly the right thing. (With the possible exception that they should have done it sooner and more decisively)

1) Drone warfare is critical to current and future armed conflicts. 2) us drone technology is currently 100% dependent on the Chinese supply chain 3) it takes time to build up a local supply chain 4) China has promised to attack Taiwan in 2027 and the US has promised to depend it. That conflict may pivot on who has the best drones in the opening, mid and end of the conflict.

Banning Chinese drones is step one in building a robust sovereign drone supply chain. It may already be too late but it sure as shit is better than waiting any longer. They’d better do batteries next or it will all be for nought.
