ah innovation. What is it do you know?
For example fighter planes. When fighters first came onto the scene, there was no need for stealth, there was no radar, then there needed something to detect the fighters, and in came radars. With radars, came the need for stealth, and here we are.
China for a long time was on the back end of the technological ladder. China is innovative, but lacks certain characteristics.
For example, how is China suppose to invent stealth when we didn't even have a credible fighter in the fourth gen. Did we suddenly grow innovative as we do have the fifth gen fighter?
Hell no, we understand the principles of advanced radars, and we have developed a need for stealth. Hence stealth.
Innovation is not a procedure, it takes genius, but within reason. A caveman can never invent stealth, but the same men given the education and background and need might.
If all Japan has is innovation, then Japan doesn't have anything at all. During the first Korea invasion, Japan was at a military all time high, just after the sengoku Jidai. However, they were badly defeated at Korea. China at that time was facing unprecedented inflation, ironically due to Japan and Spain's silver and gold trade. The first paper money and etc.
China needs to be so weak and so backwards like the Qing dynasty for Japan to be the key nation in Asia.
I am afraid within our foreseeable future that will not happen again.
Japan is strong is like UK is strong, compared to his big brother US, UK is nothing but a distraction. Today Japan is not that helpless, but with current projections. 20 years....
The question becomes, can Japan accept this role peacefully? My money is no, just as we didn't accept Japan as superior until we lost, nor will Japan accept our superiority without a lost. Not a great ending, but it is unfortunately the only ending possible.
I can see no reason why Japan will divert from our non-aggressive policy , which we have held to breast for the past 70 some years.
PS. Thanks for your post on historical dynamic. Good to see that you have some knowledge on Sengoku Jidai.
