why is the US so scared not to even touch an inch of Russian soil despite Russia's performance in this current war but will go apeshit on China when AR happens? What is the difference between the two conflicts that can warrant such drastically different responses?
It just seems strange that US won't even ramp up production to hand Russia a decisive defeat but will go total-war over a country that has a much larger economy and production potential compared to Russia.
One explanation i can think of is US internal politics. Namely, a strong contingent of Republicans are still somewhat warm to Russia and would prefer not escalating the war. Recent Republican pollings showed that nearly 50% of Republicans oppose the current Ukrainian intervention, as mild as it is, and want to end aid to Ukraine. As long as this faction is embedded into US politics, there will be an opposition voice over further escalation.
However, there is no such lobby for China. As a result, unchecked escalation leading to WW3 is a very likely possibility and should be kept in mind at all times. Even Chinese Americans are very divided and are unlikely to convince the USG of any position.
Therefore, if China attempts AR, it should prepare for the worst.
I can think of 3 possible reasons why the USA will try to suppress China's rise at all costs, even if it means a direct war between the 2 superpowers:
1, existential threat to the USA in terms of ideology and form of government. Communism vs Liberal Democracy, State-controlled Economy vs Unbridled Capitalism, Meritocracy vs Plutocracy, internal racial unity vs racial division, and Win-win diplomacy vs Zero-sum game mindset. The USA finds itself losing its luster and appeal to the rest of the world.
2, peer contest. first time in history that a superpower met its equal. The USA is now in a state of uncertainty, nervousness, and anxiety facing a fast-rising peer that can challenge it in the economy, a form of government, high-tech industries, and military developments. The USA does not call China a pacing threat for no reason.
3, The US is fearful of losing its hegemony and number 1 top-dog position to China (not to Russia which is not strong enough to challenge the US in terms of population and economy). So it is in the US interests to start a war with China when the former is still having a distinct advantage. Further down the road, say within 10 years, that advantage might be gone forever. Hence you see the US antagonizing China in every sphere and move.
I suspect there is a 4th reason, but it is politically incorrect to spell it out. It has something to do with skin color, the so-called yellow peril.
China's counter-moves?? Strategic patience, further economic development and integration with friendly countries, and nuclear arsenal buildup.
