well my friend, you just said China is a big problem to U.S. Our discussion here is military in nature. I dont see any treats from China in the near future or any time else. If U.S and China were to go at war, the first thing U.S would do is try and control the Chinese sky. This might be difficult cause China has the largest airforce in the world. But note something-70% of the Chinese aircrafts are either MiG 19s or Mig 21s. These aircrafts developed during the 1960s have no BVR(beyond visual range) capacity. This means they are useless in modern air combat agianst F-14s,F-15s,F-16s,F-18s and F-22s. The Chinese airforce has a bulk of Su-27s that can match f-16s but again since the Chinese depend upon the Russians for missiles, these Su-27s use AA-10 Almano missiles that are useless.(Gulf War showed that, Iraqi Mig-23s with AA-10 were no match for American F-15s). Also a very important aspect of modern warfare is precision guided weapons. Chinese have no reliable laser designation pods and their radar guidence and heat seekers suck. Iam not a great American fan, they are ordinary yankees for me but Iam speaking of the reality here. Chinese can never match American technlogy in any aspects for a long time to come.
