Biden defeated Trump to win the US presidential election, which made the Taiwan Tsai Ing-wen authorities who had previously bet on the wrong treasure panic, Tsai Ing-wen's biggest worry at this moment is that Trump supported his policy of Taiwan independence in the past, will Biden inherit it?
Although the Tsai Ing-wen authorities have chosen to comprehensively orient the United States and confront the Chinese mainland, the DPP itself is also very clear that if taiwan relies only on its own strength to confront the Chinese mainland, the Taiwan military will be surrounded and annihilated by the Platon Army, and it is only a matter of time before these Taiwan independence elements are thrown into prison.
Judging from the US standpoint, the factors that determine whether the United States will participate in the war and the extent to which it will participate in the war in the Taiwan Strait lie in the extent to which cross-strait relations affect the national interests of the United States. In particular, the strategic interests of the United States in the western Pacific, if placed in the Taiwan Strait and even around the South China Sea, can be roughly understood as containing Chinese mainland becoming a global hegemon, and safeguarding the strategic interests of the United States in the western Pacific.
Whether it is Trump or Biden, they have said that once there is a war in the Taiwan Strait, the United States will intervene in it. If the U.S. decides not to intervene, then the U.S. will be disgraced among its allies and no one will trust the U.S. to protect them anymore. It is important to see how deep the US involvement is, because after the war between the two sides of the strait, if the US military chooses to intervene, it may intervene with low intensity, including supporting Taiwan in terms of logistics, intelligence, and operational information, and there is also a high degree of involvement, including directly sending troops to participate in the war, deploying aircraft carriers in the Taiwan Strait, and fighting the PLA landing fleet in the waters around Taiwan. The risk of U.S. involvement in a war in the Taiwan Strait is that once the U.S. military loses or loses its prestige, then the United States' continued maintenance of its global hegemony will be taken as a joke by the rest of the world. Of course, the United States is still facing the loss of combatants, after all, in the Chinese mainland offshore operations, the Americans have no confidence in their hearts. China's reunification is a just war, and the illegal intervention of the United States will only make the anti-American sentiment of the Chinese people soar, and they will hate the enemy and unite with the outside world. In terms of combat momentum, the US military has already lost the People's Liberation Army.
In addition to the United States, there is another country that may intervene in the war in the Taiwan Strait. On the one hand, the southernmost tip of the Ryukyu Islands is close to Taiwan Island, and there are sovereignty disputes between China and Japan over the Diaoyu Islands, and China's reunification will be more conducive to China's dominant position in the Diaoyu Islands dispute. There is also a US-Japan security treaty between the United States and Japan, which also increases the surrounding situation, which lays the groundwork for the joint intervention of the United States and Japan in the "Taiwan issue" in the future.
If Japan is also willing to participate in the war to protect Taiwan, it will not frighten the Chinese People's Liberation Army at all. In terms of combat strength, the Japanese fleet has long been limited by the US-Japan security system, and its air defense system and long-range strike capabilities are insufficient, and can only rely on shore, air power and the protection of the US military to fight, not to mention long-distance operations. But even with the top-level design of the U.S.-Japan security system, waiting and seeing how it changes will still be Japan's best strategic choice. However, in general, the possibility of Japan participating in the war with low intensity is still relatively large, but once the war is fought, the low intensity may also become high intensity. Chinese mainland need to be mentally prepared from this. In addition, the western Pacific region, including Russia, South Korea, and Australia, is also the peripheral influencers of war in the Taiwan Strait, in addition to Australia, Russia and South Korea are more likely to be spectators.
Overall, in addition to the United States, Japan and Australia, other countries in the region, including Russia, South Korea and ASEAN countries, will still put national interests first, and the possibility of being a spectator is relatively large. The Taiwan Tsai Ing-wen authorities are holding the thighs of the United States and Japan, especially completely close to the Americans, hoping that if something happens to Taiwan, the US military will come to the rescue. However, the United States and Japan must also weigh whether they will die for The Taiwan independence elements. Singapore's Prime Minister Lee Hsien Loong also recently mentioned that it is no longer the Cold War era, and no country will join an alliance against China. Taiwan's Tsai Ing-wen authorities put all their eggs in the basket of Americans, and the final outcome can be imagined.
