Laser secrets have been stolen by a Chinese man. China has been stealing western tech secrets for decades. There's even a Chinese analytic bureau in fbi.
I'll let your posts go as long as they are factual on the current event but if you become ideological, there is much to discuss about the robbery, both blatantly illegal and disguised as legal, of intellectual and physical property by the West perpetrated on not only China but many many other nations, by the Americans and Western nations throughout the last few decades to centuries. This is the evil you committed unto others when you had the power so don't cry when they do it back to you when the power dynamic begins to reverse.
