If Xi does this everyone in china will know that it's an invasion! If he gives this order he will be arrested, killed or face a full blown revolution. This is absolute desperation on his part. Chinese troop are a joke. Their equipment is crap and they aren't even given body armour. Their helmets can be triggered to kill them individually or whole by their commanders or a teen hacker. I personally think the Chinese troops would kill their own officers if they got these orders. Xi is hated by the people, the PLA and the vast majority of the CCP. Plus he is in poor health and is fully exposed as a corrupt psychotic traitor. He really couldn't be in a weaker position and he knowns it. China could be economically crippled by any nation by hitting the three gorges dam with a Cruz missile. A massive Achilles heal that the CCP built themselves and will probably hit the dam themselves if the people revolt. No way will Chinese troops ever be peace keepers in the USA. This is political suicide for Xi.
