Your comparison of the the American and Chinese officer corps misses my point. The American military has since World War II been continuously engaged in missions around the world, in conflicts big and small. At almost any given time there was action to be had. Even between the Vietnam War and Desert Storm there was Lebanon and Grenada. China hasn't even done a mission on the scale of Lebanon or Grenada since 1979. The U.S. military has had not to cast about for conflicts in order to prove its mettle, the civilian leadership fed it a steady diet of engagements. But even now there are dire warnings about not pulling out of Iraq and Afghanistan, they want to keep fighting the war. They want more troops, more money, more freedom of action.
The PLA, on the other hand, has not seen action since 1991 Tienanmen Square, and no foreign action since 1979. You could make an argument that current U.S. military is war-weary, but the PLA is just getting started. While the U.S. has seen the long-hard grind of counter-insurgency, China has only engaged in blue on red exercises with no casualties.
There are more examples of the military pushing hard for war, and not just fascist countries. In Vietnam, the military always wanted more, more, more. Even 500,000 troops in country wasn't enough for the military leadership. They wanted to invade North Vietnam. General MacArthur wanted to invade China and use nuclear weapons in the Korean War, and was fired for insubordination. In 1958, French military officers led coup d'tat attempt against the civilian government to prevent the de-colonization of French Algeria. Despite the hopelessness of Algeria, the military could not fathom giving up because war was a way of life for them.
. Only idiots would train their future military leaders to think they will make their country stronger through war, as that is a sure fire way to make sure you start WWIII and will likely end up on the loosing end of it.
The role of high ranking generals in the government is to give good sound, realistic military advice and options. Their opinion would hardly be worth listening to if they are all frothing at the mouth screaming WHAAAARRRGH! as the answer to every problem, and they only behave like that in the most silly movies (or satires).
You have to separate what you
want to be true and what is more likely to be true. There have been countless military leaders with their own agendas, concerned with their own personal aggrandizement or accumulation of wealth, their own belief of what is good for the country, who for whatever reason disagreed with civilian leadership. The generals who pushed Japan into war against China and the United States in the 1930s and 1940s, among others. During World War I, the Western military leadership was notoriously careless with their soldiers' lives. They threw hundreds of thousands of bodies at enemy trenches to scrape out a few miles.
Earlier I cited the 1963 Gulf of Tonkin incident and 1931 Mukden incident as examples where the military influenced national policy through dishonesty. Those incidents demonstrate that militaries (and all bureaucracies) can work to further their own agenda. They don't just take orders.
That hardly equates to a desire to attack Taiwan for no good reason other than for the hell of it as you seem to suggest.
It is probably true that there are such feelings and desires amongst some of the rank and file, as it is only nature. But it is a massive stretch to go on and suggest that that is the prevailing view within the PLA to the point where the civilian leadership could barely keep their mad attack dog generals from throwing the leash and attacking others for the sake of it.
If a situation arrises where China could quite reasonably and legitimately need to use military force, the generals will present a military option and may well push for it. But only if it is an easy win with little risk and cost.
If China was truly threatened or attacked, there would be no question that the PLA will fight their hardest no matter the cost or odds. But you do not go starting wars of choice for fun, and even if you do, you would not go picking the hardest fight you can conceivable be in.
What you are suggesting is in effect that the PLA generals will push to attack Taiwan out of boredness. That is just not going to happen.
Here you go with the strawmen again. There is a psychological undercurrent that will influence the PLA's thinking in a "pro-use-of-force" direction. That undercurrent is a desire to try out their new tactics and equipment, and to prove themselves to their superiors, their countrymen, to the world. The military is not going to attack Taiwan out of boredom, I never said or implied such, but rather this undercurrent would push them increasingly in a pro-war direction. They need a pressure release valve, just like the U.S. military has a constant plate of conflicts in which military blows off steam.
Your argument that China is different has to do with their legacy as a victim of foreign powers. You said the century of humiliation makes the Chinese more sympathetic to foreign countries suffering under foreign militaries. Well, China sees Taiwan, the Spratly Islands, and Daioyu Islands as internal conflicts because it claims the territory as its own. China's lack of control over those islands is seen as a continued grievance from the century of humiliation.
Finn McCool made a good point that China has a chip on its shoulder, and you seem to agree. They were wronged by the West and Japan in the 19th and 20th centuries and are finally coming back in a big way. They've got a lot of new stuff and tactics to try out. The CCP may be firmly committed to "peaceful growth" but the military will have its own agenda. They have a different organizational culture than the Party. An organizational culture, that, in similar circumstances in the West, led to a push for war.
