They already know how to do that. Now they come here to remain competitive by stealing cutting edge research and technology. Their plans to defeat us are already underway, and have been for decades. Control the manufacture of our goods and medicine, spread famine to our crops, influence or control our propaganda outlets and debase our currency, to name but a few. They know they would lose in a military confrontation, so they are going with 'death by a thousand cuts'.

Thankfully, our President recognizes it and is having none of it.
