China used to make everything, including our chips and circuitry for our military. They put back doors into everything.
Trump initiated a purge of all chips manufactured in China from our military.
I also want to point out that the SES is the true deep state. Thousands of political appointees placed by Obama are still in control of "advisory" positions in almost all departments of government. I believe Trump has kept them because all they can do at this point is hurt their own cause, and bury themselves.
Last thing I'll point out is that Obama still receives the presidential briefing. Our law says that any ex-president that wants to, can receive the intel briefings. I think only 2 have: George HW Bush, and Obama. He knows where Trump will be and what he will say when he gets there.
