Good point concerning high tech unknown equipment. I heard one of the former Directors of area 51 who said on a TV program that whatever the American public can imagine concerning technological advances at area 51, Area 51 advances are 50 yrs ahead of that!

The United States possess one of the only military's in the world capable of defeated China on the battlefield, but there is an exception to this and that is what are the goals in defeating China. An invasion of Taiwan could be successfully repelled given enough time too build up forces. Chinese intervention in a second Korean war could be overcome given proper preparation. But mind you that the U.S. would suffer a great deal of casualties in a war with China so in what context are we choosing to fight China, for what reasons will decide our level of commitment. China would prove a worthy and powerful adversary today and undoubtedly has a very good assessment of U.S. capabilities and plans of countering that. With that said The U.S. undoubtedly has planned out every scenario in which a war with China could happen and plans to defeat China in these scenarios. No doubt the U.S. has a better military then China and U.S. ability to project these capabilities are far reaching to every corner of the Earth. We have the worlds largest Navy, larger then the next 13 countries Navy's combined. The U.S. has 10 active Carrier Groups with 2 Carriers in reserve.and close to 400 aircraft at their disposal. The U.S. has a highly trained, extremely well equipped, and very capable leadership. The U.S. military has a high amount of combat experience and lead personnel. Undoubtedly the U.S. could defeat China on the battlefield, but why would we go to war with China and what would our level of commitment be is the question. This would determine the level of support by U.S. citizenry which is vital to how we fight our wars. Let's hope that day doesn't come because I suspect there would be a high price to pay in a war with China in American blood both given and taking.
