This sniippet is really a libertarian condemnation of OUR foreign policy.
To address your question. Not long ago a friend and I were discussing this very issue. He said "One day we will wake up and find our harbor filled with Chinese warships."
In consideration of the city we were in, where Chinese interests had bought up entire blocks, entire neighborhoods, torn everything down and rebuilt. The "gifts" of infrastructure. The new civic center. The gardens, the refurbished municiple pool. The transformation of the local slum into a trendy new arts district. All of the new business that moved in and given employment to Americans is owned by the Chinese.
Chinese investors are building a huge solar energy plant in southern Nevada. Including the manufacturing to make the parts to go in the solar panels. The apartment buildings to house the workers, shopping centers, medical offices, a hospital. All being built by the Chinese. The Chinese are building an entirely self-contained city in Iowa, just the first. 100 Chinese teachers arrived this year just passed to teach Mandarin in American schools. The first of many.
My answer was "By then no one will care".
That's not even really true. It's not that no one will care. People will care very much. China has been quietly buying the gratitude and loyalty of Americans for a good many years without anyone noticing much. They have been hiring the best and brightest away. Entire companies have been lured off to China. Steve Wynn finds China the new land of opportunity and he's not alone. What would happen if China invaded? Millions of Americans will owe their jobs to China, their homes, their children's future. China HAS invaded. It might not have quite gotten to your street - yet.
The proper question is, when China has fully saturated the country and sapped the Will of the people to oppose them what will be their next step?
China would and will never invade the US.
Too late!
If you mean that China will never invade the US militarily, that's true, but they won't have to. To be more accurate, it's not necessary.
