China has plans for that its tactical emps and cyberwarfare on enemy naval superiority and airforce. If America doesn't have access to her navy or airforce including her allies then China wins. Those modern jets have to be connected to something digital like satellite connections or radio this is a vulnerability that could be used to send code that could disrupt the fighter jet/bombers' computer system. It could fool the pilot into reading decoy radar blips to try to get them distracted to compensate for a smaller airforce or even navy. They probably have plans to defeat these manhattan project style hacking attempts; but so does China to circumvent their digital defenses against hacking attempts on fighters and bombers including drones as well. http://www.cnn.com/2015/05/17/us/fbi-hacker-flight-computer-systems/

Now, imagine what another major power can do if a civilian can do that to a commercial plane imagine what they can do to tanks, drones, attack helicopters, fighters, and bombers to be used against us by Chinese Manhattan Hacker Projects?

EMP and cyberwarfare would target American infrastructure which is equivalent to a third world country. No electricity then no American supplies her allies would also be targeted by emp and cyberwarfare to target their food grid. No electricity for her allies then no food and water which means no supplies for your troops, tanks and etc. America's infrastructure is vunerable to defeat if they don't find a way to protect it from emp. http://www.businessinsider.com/countries-with-better-infrastructure-2013-3

Assuming that China can be occupied is nonsense. No country will allow itself to be occupied after defeat without using nuclear or biological weapons on enemy turf. If they left them unoccupied in a possible defeat on either side then there would probably be no nuclear war.

That's where cyberwarfare and electronic warfare come in to unconventionally without nukes defeat the us army, navy and etc. No naval vessels left; then no defeat of China. China hacks the USA all the time and they are more likely to strike with a new stuxnet that destroys aircraft carriers and all other naval vessels that are computerized and not mentioning computerized jets and bombers and even drones would be subject to electronic warfare. They probably even have plans to bypass the American defense systems that counter cyberwarfare and electronic jamming by spying. China is one of the trio cyber superpowers in the world and probably has the best hackers in the world. http://www.dailymail.co.uk/news/article-3181179/Shocking-map-shows-600-times-Chinese-hackers-stolen-American-secrets-past-five-years.html

If any computer even offline that was made in Asia was used to make these black projects; then they are probably infiltrated the latest black projects because of the mass numbers of spies there is no easy way to track them after realizing that government surveillance programs don't stop terrorism as much as they should

No confidence? Look at history when Germany invaded Russia/USSR and look at would happen if China was invaded by USA with the world's largest economy by ppp in China then China can shift their economy to mass producing weapons, tanks, missile defense, drones and all the other equipment with the stolen tech from America. Now, its stolen American tech the most advanced in the world vs America but in numbers. According to scientific law it mostly depends on who uses their numbers more wisely. It is most likely knowing that the Chinese have the history of Sun Tzu on their side. Its science https://en.wikipedia.org/wiki/Lanchester's laws

This is what China would do to deny America from attacking them

1. Assuming China's anti ship defense weapons are successful at denying America's aircraft carriers and naval vessels within the asian pacific area. Including Australia and everywhere else withinn Chinese reach which includes all of the middle eastern bases and the ones near India if any.

2. China gets support from new Russian missile defense systems like s-500 estimated to be mach 32 sorry no way to defeat this air defense so say by by to f-22 and f-35s and stealth craft they are now outdated so now it depends on who is able to use their craft since America is denied from using their aircraft they lose air superiority and ground superiority since there is no way to provide equipment and troops and tanks and etc.

3. Stealth bombers and weapons are now outdated so everything relies on cyberwarfare. Now, its a game of uncertainty so does m.a.d. assumming no nuclear weapons in this military conflict if America uses nukes then the world including America becomes extinct and nuked.

Will America risk the extinction of the human race by using nuclear weapons on Chinese military bases knowing that China's nuclear policy is to strike major metro areas including the west coast and east coast and midwestern major metro areas. Which is why they have a smaller nuclear arsenal because they don't target military bases but civilian targets as a form of deterrence to accept defeat from Chinese forces? If it remains in a non-nuclear conflict America will lose and if it is nuclear; America will be destroyed so both sides lose if it goes nuclear.

Also, assuming that s-300, s-400 and s-500 makes cruise missiles unable to penetrate bases so you have to use decoys so cruise missiles cause limited damage.

Also the western and southern flanks are protected by mass produced s-400s and s-500s and denial weapons that target military bases.

China has a better chance of winning if they use their numbers and economy to mass produce stolen American tech to outgun the Americans with their own technology. Not to mention that the pollution levels would be skyhigh in China from the sleeping giant warmachine.
