China's economy is collapsing under the Tariff's they will not win. They need the manufacturing base for an economy. So if Trump's tariff are successful and force all the American business to leave China as their benefits for being there are gone with the Tariff's the Chinese lose. If the Tariff's just keep going on the companies will slow lose all their profits and have to keep rising prices on their goods so they will lose. China's economy is already started to strain badly it was only a year or so ago they also had a total economic collapse.
China is a paper tiger and Trump has shown this. Even if this forces China into a war they will lose everything. Eighty percent of their nation is not livable regions and most are crammed into a small region a few major strikes and their whole nation would be destroyed. Also the majority of China needs food imports to keep their population feed. When their economy collapses there is going to be riots against the Communist regime and its all going to fall apart. That is why the Chinese are clamping down on separatist groups now.
NATO is just a reason for Judeo America to put military bases everywhere like in Germany to keep control over the population. The collapse of the Judeo American empire would force all American bases to close down and that means the end of NATO. Without China its not that important.
