RE: 2nd Chinese Stealth fighter J-31 Ist flight
the worst thing we can do is under estimate the capabilities of your enemies or potential enemies. We experiences that during WW2 and the Vie Nam war. I dont doubt that you are educated or well read but yoou dont know what you dont know until its to late. remember, the Chineese still have the Russians who supply them not only with the materials but the technology.
