100 Million soldiers, with no food, during winter? I highly doubt it. They would have been stockpiling resources in order to push any sort of military campaign forward. And in todays military, the most advanced equipment can win the day over numbers.
Iraq described themselves as a 1 million manpower strong army.
Which was reduced to guerilla fighters in less than 100 hours of combat during Desert Storm 1. The Iraqi's at the time had the most advanced military infrastructure that only the Soviet Union could provide. Which turned into so much garbage in less than three days.
The most advanced chinese arms technology is only reserved for their most fanatical units. Otherwise china is still boasting quite a bit of military technology that hasn't really advanced from their current 1960's hardware. China's philosaphy is the same as the D-Day at Normandy beaches. Throw enough troops into the fray, and you will break through.
The most optimum time for an invasion from China would be Spring and Summer. They would have to occupy and pacify an entire country by autumn, and then fortify just as snowfall before winter. Besides the same tactics of IED and guerilla warfare that the US had to fight both during the Iraq and Afghanistan war, the Chinese would have to rely heavily on support from the conquered territory.
The other problem china would face is...yah they have 100 million men...without women. And the chances of rape atrocities will abound in any such campaign. The chinese government never cared about apologizing for their police state brutality, and they would never earn the hearts of minds of conquered citizenry when reports of mass rapes start pouring in. And in the world news, when those atrocities start getting to the newspapers, the world will be highly pissed off. "War for Land Or for Concubines," will read in the headlines. This will hurt their world image, but if the world is less willing to fight to push china out, then china in the long run would win. If there really is 100 milion men, and their consripted or actually serve. I'm pretty sure they can take every last IED, and just keep sending more troops. And since the chinese are so good at building walls, support from other nations would be near impossible.
Now the Chinese government has taken all this into account. Their socialists, but their not stupid. Their main objective is limited pokes and prod actions, that force an opposing side into "Rash Action". This rash action would be seen as a military excursion by the chinese government, who would feel the need to protect their borders, by advancing military force against said Rash Action. That means a quick desicive war of occupation.
That is why china backs the North Koreans, when the North fires rockets into little South korean islands. Tibet, had no strong influence in the world, or military power. Always testing their borders with Russia, because parts of Russia where the Chinese poke and prod are literally strips of uninhabitable land. Whatever they can grab, they will take. Whatever shows strong resistance...they continue to poke and prod to induce the enemy to make the "First military action", before they declare a state of emergency or war.
If China goes to war. It will have to be a quick decisive war. They don't have the resources to field a starving population, and a military machine at the same time. They pour all the resources into military force, chances are they won't have anything left in case revolution takes hold. That's another thing China's government has to watch out for. If they go into a military campaign...do they have enough troops back home, to prevent an all out insurrection amongst the populace?
There's a lot more questions than there are military options. And China's military high command knows this.
There's about a dozen more things that I havn't even commented on that will directly effect China if they went to war. One of them being the World Agency that helps ship food to China on a daily basis. A lifeline that would be cut short if China actually opted for the war scenario. If china is importing food. The vast majority of those imports would come to a dead stop. China's Economy, the yuen, would also come crashing down as each nation placed embargoes on them.
Pretty much the only thing keeping China from the military option is Food and their economy collapsing due to embargoes. Though the embargoes would have to be placed after china went to war. China has already stated that any embargoe against their country would be seen as an "Act of War". They have stated this in the 1960's, 70's, 80's, 90's, and again in the 21st century.
China is a toothless dragon. Lots of fire, lots of rumbling, lots of noise. But their a hallow pinata, ready to be clobbered if they did anything stupid as start a war first.
Now if Einstein hasn't figured any of this out...you better believe, I would never vote for him in any political office. Especially if he doesn't understand the nuances of how military force and sociliast governments actually work.
