You'd think that it is nonsense to argue that it is racist to target Chinese nationals to stop China's massive intelligence effort against America, but you'd be wrong.
Good grief, people, are we supposed to round up the usual Canadian suspects to stop Chinese espionage? Of course we need to closely examine Chinese nationals.
As you may have read here, Strategypage calls it a "thousand grains of sand" approach that recruits or coerces Chinese coming to America or even Americans with family in China to report back to China or bring even small bits of information used to fill in a picture they build with many means.
China is doing a lot, most obviously online, but including those Confucius Institutes on our campuses.
And China works hard to prevent Americans from getting information unapproved by China about China.
So yeah, we should scrutinize Chinese citizens in America. Such scrutiny would help protect Chinese-Americans from being coerced by Peking into espionage, it should be noted.
So yeah, it really is a whole of society effort by China. An authoritarian government coerces much of that full court press, but it is a massive threat nonetheless.
