I don't like China for how it is behaving with my country but it is rich to talk about "invasions" when all the invading in the past half a century has been done by a Sole Democratic Superpower and its lackeys. Cannot believe I am having to defend China here but here we are!

On the other hand, we can't tell if the US has a goal or not in the middle east or if destabilising countries is the geostrategy unto itself.

People really need to dial down the hype, engage with the real world where large countries get to have a sphere of influence and start talking realistically about what behaviour is tolerable. I still haven't heard anyone make a case for why we keep hitting the Russians given what acceptable US foreign policy looks like. One of the two is worse and it isn't the policies written in Cyrillic.

I think it's a safe bet that China will invade precisely when they think this won't cause them severe negative losses.

This will likely be when Taiwan finds itself no longer a close ally of the USA, nor of global geostrategic importance.

Of course, "safe bet" doesn't mean "in all possible timelines"; they may end up echoing the Bay of Pigs, Hormuz, or stumble against the hubris that turned the assassination of Archduke Franz Ferdinand into a world war where all belligerents had the mistaken belief they would win.

The "dicatorship" of China never implemented such a thing in my country. USA "democracy" did.

Democracy is when you drop a ballot every two/four years, and the elected officers ignore you while they take millions of donation from wealthy donors. Dictatorship is when the unelected representatives work their ass off to better the lives of the average citizens, because they're afraid of a revolution.

(P.S.: Xi Jin Ping is as unelected as the British Prime Minister, but I don't see people calling the UK a dictatorship.)

You're confusing "ally" and "vassal". Allies are countries that send troops to help you in war.
