The U.S. will Have to fairly Handle China, Russia, Iran, etc.
It is thought that the era of WWIII has finally come with the Ukraine war and the Iran war as well as U.S.'s invasion into Venezuela.
As for the Iran war and U.S.'s invasion into Venezuela, some Japanese political critics say that the real target of America is China. Indeed, China has provided air defense systems to Venezuela and Iran, but those Chinese systems have been found useless. China has provided those radars, anti-air missiles, etc. to Venezuela and Iran as exchange with crude oil imported from Venezuela and Iran. But, those Chinese air defense systems have been found useless against American air attacks. China looks losing face in Venezuela and Iran, which every country observes.
So, the Chinese plan to invade into and occupy Taiwan by the end of 2020s might be changed as the Chinese military has to admit that they cannot cope with the direct armed conflict over Taiwan with the U.S. military. Indeed, if China launched military operation against Taiwan, the country with support only from Russia and North Korea would have to fight against America and Japan as well as Taiwan. If China cannot show military dominancy at an early stage of the possible war against Taiwan, it should lose support from Russia, North Korea, and other pro-Chinese countries. Then, a civil war might happen in the mainland China.
However, in this case, unlike the situations in WWII, Japan would not interfere with China, but the United States might judge that it cannot leave China in a civil war, since Russia might come to cut in.
So, in this era of WWIII, the possible Chinese civil war would be another big factor in addition to the on-going Ukraine war and the possible Iranian civil war.
From a historical point of view, it looks natural that autocracies like China, Russia and Iran should be replaced by their successors with democratic political systems. The era of autocracies should be passing away.
Anyway, a nation that can represent the Earth against space aliens should be the United States of America with advanced democratic systems, defense systems and economic systems as well as religious freedom.
Truly those autocracies like China, Russia and Iran lack something important which the U.S. has. On the contrary, Japan after WWII has followed the U.S. taking in many American ways of life and society has completely abandoned the possibility to have its imperial house act as the head of autocratic imperial Japan. The emperor of Japan has no authority other than a symbol of unification of the Japanese people. Politically, the prime minister of Japan is the real head of the nation. And, the status of the Japanese prime minister depends on dominancy of the Diet, the national legislature. The Japanese Diet is run properly in a democratic manner.
So, it is a big problem for Japan that China seems to have sent may spies and espionage agents in and around the Japanese Diet throughout many years after the normalization of diplomatic relations between Japan and China in early 1970s. Indeed, there are many pro-China politicians in Japan.
However, as Sanae Takaichi, an anti-China politician, got landslide election victory as the first female prime minister of Japan a few months ago, the pro-China politicians in the Japanese political circles lost their momentum. On the contrary, China has launched anti-Takaichi campaign; Even a Chinese diplomat stationed in Japan wrote in the Internet that he would cut Takaichi's head off if she continues to take a strong stance against China over the Taiwan issue. However, this Chinese diplomat seems to misunderstand real intension of the prime minister's words issued in a session of the Japanese Diet; she only expressed the possibility of Japan's supporting U.S. fleets coming to Taiwan to save Taiwan from invading Chinese fleets and troops. Japan has to help U.S. fleets as Japan has been an ally of America for many decades after WWII, although Japan has a rigorous peace-oriented constitution.
So, many Japanese people now doubt the intellectual level of Chinese diplomats. They seems to be unable to understand democratic commonsense. Chinese in America might look similar human beings to ordinary Americans, but there is no democratic commonsense in their brains. Even many Japanese have recently confirmed that Chinese people lack something democratic so dangerously and foolishly.
It is not good to rely on China and similar autocracies that cannot understand or respect democratic commonsense in any fields.
Finally in the era of WWIII, the U.S. will have to fairly handle China, Russia, Iran, etc. to introduce true democracy into these autocracies.
However, nuclear weapons should not be used in coming wars and conflicts, since space aliens should warry that the mankind in the Earth might destroy or contaminate fatally the nature of the Earth with radiation contamination.
John 3
31 The one who comes from above is above all; the one who is from the earth belongs to the earth, and speaks as one from the earth. The one who comes from heaven is above all. 32 He testifies to what he has seen and heard, but no one accepts his testimony. 33 Whoever has accepted it has certified that God is truthful. 34 For the one whom God has sent speaks the words of God, for God gives the Spirit without limit. 35 The Father loves the Son and has placed everything in his hands. 36 Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them.
