I'm now even more convinced NATO will do nothing if China reunifies Taiwan by force.There are many things China can learn being a bystander (kind of):
1. what countries are hardcore US allies even this war is nothing to do with them
2. what sanctions are from US and its allies
3. military operations on both sides
4. worldwide reactions
I think China should give Putin a big medal and well prepared. Let's wait for the inevitable and compare notes.
They are sitting by and doing nothing while a 1 trillion power takes over a 600,000km2 sovereign country directly bordering EU and NATO, 250km away from Warsaw. No way in hell they fight a 20 trillion superpower for an unrecognised 30,000km2 island halfway across the world.
