Zakharra, don't take this personally, but there are times I think you like being obstinate for the sake of obstinate.
If you actually open a map of Asia and look at it, China has no major options on moving overland without sparking a major war. A war big enough to potentially cripple or kill them.
Canít go north, because that goes into either Russia or former Soviet territories which you can be damn sure the Russians will defend, if for no other reason than to make sure the Chinese donít get them. But there is oil and other valuables in some of those regions to make it more interesting.
Southwest isnít much of an option. Care to see what the second largest national population can do to the first? Attacking India would be suicide because they have the numbers to play the attrition game on their own soil, and that is a BAD military option to partake of.
Plus, want to place your bets on Pakistan? Would they stay out of it, or get nervous enough to set aside differences with India once there was enough Chinese troops on their border? I donít know the answer to that any more than you do, and please donít pretend you do, but either way both have enough nukes to kill a few million encroaching troops.
Further past, into the Middle East? Actually I wish they would, because it would turn the eyes of most suicide bombers and fanatics to Beijing, not NYC or Moscow. Have fun containing all the explosions going off in your country while most of your troops are trying to suppress the region. Unlike Fortress America, China wonít have a buffer zone of the first and second largest ocean to help screen who gets in or out, even if they shut down all air travel.
Japan is out of the question, because it would result in a devastating American attack. Last I checked, the American/Japanese defense pact is still in place. And while Chinaís eyes are turned to the Pacific, any bets on who might or might not want to take advantage of that further inland?
The only real option is south; specially Southeast Asia. Nobody would likely break a sweat if they took Burma, maybe even North Korea. But Vietnam, South KoreaÖthereís that specter of US intervention again.
That opens up the concept of transporting troops en masse by air or sea. Depending on where they were headed, the US could deny them landing. As it stands, we can drop more troops into Taiwan than China can.
And of course Taiwan is the lynchpin in all this. Would the US go all out if China took the island? Likely not, but we could make keeping the island VERY painful for them.
And as far as China not caring about war with the US, yes they would care. YES they would. Because our economies are linked enough that thereís no way either of us would survive it economically. The US arsenal running in overdrive could make their population of 1 billion plus into a few thousand stragglers, no matter what happens to the US. China would not just be damaged, China would be forever dead as a nation, and unlike the Islamic cuckoos, China would be under no illusion theyíre going to heaven as a dead nation.
