Is that supposed to make Americans feel any better? :) Seriously the Chinese government still thinks of Taiwan (and on a bad day Korea) as one of its provinces and given its location it could easily become one again.
International apathy is at an all time high, thanks to most countries dealing with internal political issues (which in most cases involve rigth wing groups and fake news)
Taiwan is an island. Sending a column of tanks there isn't something the PLA could just do overnight. They'd need to get a warship past Taiwan's naval and aerial defenses in the first place before they could even think of invading with tanks.
Yeah yeah, sure, it could happen. And if it did the last thing any of us would be concerned about is whether or not AMD shared innapropriate technology.
Just wait for the Americans to run out of cash to pay for the aircraft carriers around it...
