ONLY 750K colonists? Big deal. We’ve got millions of invading barbarians in the US. We got a more serious problem MUCH closer to home.
Well, they're not "barbarians". But your numbers do make a point. 750,000 Chinese in a continent with 800 million people is hardly something to worry about. There are 10 million illegals here in the US. A nations of about 300+ million people.
