If a plane or tank or ship has Chinese computer chips in them with back doors built into the chip the the Chinese can use to access those systems. A tank’s targeting equipment all of a sudden might not work. Helm in a navy ship may all of a sudden not respond. Weapon systems go off line. Planes like F22, F35, B2 etc that rely heavily on computers for stability would drop from the sky. Communications go down. Get the picture. This is old news at least to us. The President After the first year kept broadcasting to the world we have the greatest strongest military the world has ever seen. A big part of that was neutralizing this Chinese computer chip threat. Different subject: you are correct 7/10 plane crashes are no accident. Remember in the beginning when the secret service stopped a jet blue plane from taking off. SS got wind that the auto pilot was going to be used to bring the plane down.
