I really don’t think the USA can afford to let Ukraine fail. They are basically committed to destroying the Russian economy now, and having them lose the war in Ukraine is an important part in that.
If Russia is able to defeat Ukraine, end the war and stabilise the situation, they will be in a better position to convince countries to work around the sanctions they are facing, which would amount to an end-run around the dominanc e of the US dollar.
So this is accurate in my opinion, but you're essentially saying the quiet part out loud. You're saying the war has nothing to do with saving Ukraine, but rather protecting the hegemony of the US dollar.
I suspect if everybody understood that's what we're really concerned with, support for Ukraine would drop precipitously.
