The Golden horde's strategy/warplan for both sides
The following is somewhat biased toward the US. I am basing this on the condition that the US is out of Iraq and the Taiwanese army:taiwan does not revolt and welcome reunification. Read it, I put a lot of work into it.:type
Well, I've thought about this for a long time. China would be best served by simaltaeneously attacking Taiwan with a massive missle barrage and hitting Kadena Air force base and base facilities on Guam with ballistic missles and submarine launched cruise missles. (Unless Taiwan starts the war. Then the US wouldn't intervene. But if China is attacing first, then it cannot pass up the chance to hit American regional assests with suprise. Kadena might be left untouched because it is on Japanese soil. An alternative would be a large sub-cruise missle strike on Diego Garcia, severely effecting the US capability to deploy foces into the area.) China then would prepare its forces for an attack on a lone CBG, particularly the weak Kitty Hawk. It is closest to the combat zone and would be the first on the scene. If PACOM is foolish enough to tell it to engage the PLAN without another CBG or two supporting then there is a chance the PLAN could achieve a signifigant enough concentration of forces to destroy the Kitty Hawk of at least damage it and/or its battle group. The loss/damaging of a Carrier of a number of lesser ships would be a major blow to the morale of a US public already confused about why it must defend Taiwan. During this period the US would be using its assets on Guam, Okinawa and Diego Garcia as well as B-2s to make cruise missle strikes on Chinese beacheads/troops massing for an invasion/itinerant PLAN forces (depends on progress of Chinese forces against the Taiwanese.) The US woud also be sending as many carrier battle groups, subs and other forces into the area as it could.
At this point the strategy becomes a bit hazy. It all depends on how the Taiwanese are doing. If the Chinese are already in Taipei by the time the US has suffucent forces in the region to take the fight to the Chinese, the US government will probably decide to negotiate. Dislodging the PLA from Taiwan is not something any commander would relish. However, if the ROC (Republic of China) forces are still fighting and the Chinese are contained to a beachead, then the US will continue in its operation.
Let's say the US did continue because the PLA did not have control of Taiwan. The PLANs destruction would be imminent at this point, and it would be the USNs first target, especially its capability to reinforce its troops on Taiwan. Now, the US would go about hunting down the PLANs subs, supporting the ROCs army (and possibly US marines too) and conducting strikes against the Chinese mainland. The PLAN would use, and probably lose, its Sovremmeny destroyers and other modern ships in an attempt to take out a carrier. They would not stop the USN from turning the tide, but would inflict losses, especially with help from the PLAAF.
During this period there would be a battle for air superiority over East Asia as what is would be left of the ROCAF, US carriers and land based fighters took on the PLAAF. We all know who the winner would be. The US would take losses, losses it hasn;t see since VIetnam, maybe even WWII, but it would definetly win. There is a difference between air superiority and supremacy. The US would only have superiority and would not be able to hit the mainland at will. China's air defence is far too capable for that. Not to mention the fact that the PLAAF could swarm isolated strike forces with old Jians. So most of mainald China would not see the war. The US might "turn out the lights" in Beijing or Shanghai if it felt it had to make a point.
At this point there is very little China can do offensively. Its navy has been used up and its airforce has been (basically) defeated outside of China itself. However the US is still suffering casualties. Chinese ballistic and crusie missle still are fired at US ships and bases. The ROC is being supported by the best units the US has as it slowly forces the PLA off of Taiwan. This is where my vision of the war ends. I cannot predict what happens now. I have a few thoughts though.
China negotiates. It is allowed to keep the Pescadores as well as Kinmen and Matsu islands. Taiwan is declared independent. The US would start the negotiations with what are understood by both sides to be throw away claims, such as China paying an indemnity and additional territorial concessions to Taiwan. This allows the Communist party to claim major victories in negoiation. Taiwan would probably be recognized as permanantly independent, but if China came out of All of the stuff that happened above with more militray forces left than I predicted Taiwan might stay in its state of de facto independence. The US would probably agree to secretly drop a lot of things that bother the Chinese, such as hosting the Dalai Lama annd bothering it about human rights. However, the US would still be the big winner. It woudl proabaly forces China to drop its support for Iran, and let Central Asia be the US's sphere of influence, in addition to the fact that China's worldwide influence and military power is drastically curtailed. The peace would not last though. China would be resentful and would continue rising, except this time with a want for vengance, like Germany after WWI, except growing stronger instead of weaker.
The other option is that China decides to make the war truly globabl. It puts all the diplomatic pressure it can on Russia, Pakistan, India, South Korea and every other country it can to withdraw suppport for the US. The US would be feeling the economic effects of war by now. With Chinese products off the sheleves and oil through the roof, the US consumer would feel the burn. And if China retired behind its ari defence system, the US couldn't do much. Raids on mainland China would be too costly. All the while the US is loosing valueable planes, missles and (for a time) ships that are too advavnced to be replaced quickly. At this point, as long as the war goes on, the US will suffer more than China. China could start aiding the Taliban too. That would cause problems, even if US troops are out of Afghanistan. The US could raise the price of a continung war for China by making landings on the Chinese coast. These landnig would not be intened to take large parts of Chinese terriroty. The US would establish a beachead in a defensible area and expand it, until it had a small pocket of territory on Chinese soil. Then it would fortify and protect itself from being overrun. Done in economically vital areas, such as the mouth of the Yangtze, it would hust the Chinese. When the PLA tried to overrun the pocket, it would be hit by everthing the US had. The idea is the same as Khe Sahn. Intice the enemy to concentrate his forces then hit him with superior firepower.
I'm not pretending to be able to predict the future. This is what I guess would happen, based on my knowledge.
