Thanks to open borders, I have no doubt that there are thousands of sleeper agents in the United States.
It wouldn't take much for them to cause massive disruptions, even using relatively "dumb" techniques.
The damage would be even worse if strategic targets were hit, along the lines of what Jeff Head describes in "Dragon's Fury". I also have no doubt that the Chicoms already have networks in place to carry this out in the event of a future war over Taiwan.
Then they would laugh as our government passed even more laws to harass, not the terrorists, but the American people.
With ZERO training ...
What are you guys on anyway?
