In geopolitics the country with the biggest stick can do whatever they want since there is no way to enforce International. Russia and China can whine and cry all they want that we’re in their part of the world, their spheres of influence if you will, but in the end there is really nothing they can do about it. The US has the biggest stick on the planet. Also, do you know why China has not attacked Tiawan? Because the internal honest military calculus they do tells them they would get their asses whipped. If not, they already would have attacked it. They understand the truth about the balance of power, meaning our military capabilities vs the CCP’s military capabilities are still totally in our favor. And remember, Chinese numerical superiority means bupkus in the real world of military conflict. Our Navy as poorly trained and maintained as it is compared to our Navy pre obama, is still way more technologically superior to China’s and Russia’s that both know the real score. This is the reason why Taiwan is still free and Japan has not been attacked. You can bet though, the moment the CCP’s military calculus tells them they can succeed, they will waste little time attack the US, Taiwan and Japan.
Of course the above is only true if China is being reasonable and truthful with itself. If Xi gets into a position where his status as CCP Chairman is threatened, and if he thinks attempting to invade Taiwan will protect him, then he will attack Taiwan, and the US and Japan too. Personal survival is the only thing a communist clown like Xi and his fellow Politburo members really care about.
Should have said:
In geopolitics the country with the biggest stick can do whatever they want since there is no way to enforce International Law.
We can probably handle Russia or China separately, but what about both simultaneously? Bear in mind we are not doing well in the hypersonic weapons area and that Russia has developed some truly devastating weapons.
Concurrent conflicts could become very problematic, especially for a government with very weak leadership in a country beset with numerous internal problems and divisons.
Even without US help Taiwan would brutalize the PLA’s snowflake politically reliable army led by “generals” who purchase their positions, in cash.
