China has the population to send millions of spies here.
If we caught them all tomorrow - AFTER letting them in, AFTER letting them gain access - WHERE WOULD WE INCARCERATE THEM ALL?
This case once again demonstrates that we are committed to submitting to our enemy(s) either by design or collective failure at all levels of government.
Red China does not have to send spies over here [the United States of America]. If they wish to learn any of our secrets, all they have to do is to go to a Democrat Politician or FBI Agent and ask them. For a small fee, they will tell the Questioner anything they wish to know.
