Depends. You assume it’s the US taxpayer’s responsibility to defend west Asia and Eastern Europe.
Why?
A lot of nations are pouring money into Ukraine. The West has a world vision that runs counter to that of Russia and China. We cannot fight them.
We screwed over what the "domino theory" was supposed to be. It was never to be defend everywhere. Vietnam was never worth defending. If China goes in there, or many other nations, we can react politically or diplomatically, but it would not be at all in our interest.
But Taiwan? We need those chips and we need for China/Russia not to have unlimited super modern chips. That would severely eat into our quality edge.
Similar with Russia. There are a lot of Central Asian countries that we have no interest in. Our interest is showing allies that used to be occupied by Russia we have no interest in seeing that happen again.
A world built into the image of dictators is not in our interest. Our response is to identify critical areas and hold the line. A line not requiring American blood. If we are not willing to hold the line with dollars, shouldn't China and Russia fully believe we will never hold it with blood?
