That may have been meant as a joke, but China is the newest colonial power.
Foreigners cannot buy land in China.
Chinese however can buy land here, and we are running a (massive) trade deficit with China now.
So not only does China not allow foreign land purchases, we continue to support their government factories.
China has five times America’s population.
Wake up people.
In a weakened America, any perceived or fabricated threat to Chinese nationals might be used as a pretext for Chinese military intervention to “protect them.”
