Some of you folks live in fantasy land. The Chinese may have a very large military, but they do not have the logistics to move an invading army into North or South America. Their only chance of success would be to get the Mexican government to let them pre-stage armor and support vehicles in Mexico near enough to stage an invading army. Before they could build up to a successful level I am sure the spying apparatus would see what they'd be up to. And yes we are watching the middle American countries for that possibility.

We did not infect the Chinese. That would be ridiculous. They, with their citizens, have been going around the world spreading it.
