Relying on Chinese hardware is giving the Chines a broad avenue to all information that their hardware touches. Their back doors in every device is why the military and the airlines and some industries have been ripping out and replacing all the Chinese components they have put into their systems over the last decade. Chinese components are cheap to purchase but extremely expensive to use. A Chinese chip on your/my motherboard is likely sending every bit of data on the computer back to the Middle Kingdom.
You're right - but on the lighter brighter side our 'intelligence' boys spend billions - our CIA and FBI boys - trying to find out that some pervert five degrees away from Putin is into child sex and can be compromised. Oh and that Trump once paid off some porno slut to stop her from telling his wife - you know - blackmail...
So the destruction of our country's not that bad... the 'intelligence' boys who are suppose to protect us are playing cowboys and Indians with a country that has a smaller GDP than Italy.
Do you find it scary as hell that YOU arthurus know more about REAL threats to our country than our corrupt overpaid 'intelligence' thugs?
Here's what we should do - assume our enemies will do everything they can to harm us - then spend our money making every vulnerability tougher so they can't hurt us. Manufacture our own computer equipment. Keep industries that could be converted to war manufacturing if necessary... find out where a war would cripple us and do the work NOW to avert future shutdowns...and disasters. Plan for the worst - hope for the best.
