It has been extremely obvious to everyone who isn't an incredulous lib (ie the ledditor refugees from lemm.ee et al) that the US doesn't actually give a shit about Ukraine and is more than happen to fight Russia to the last Ukrainian. Why else would the US constantly ship overpriced wunderwaffen that the Ukrainians can barely use due to lack of training time while at the same time gobbling up Ukrainian state assets? And as we saw with how Afghanistan ended, the US will inevitably pull support, most likely because of Taiwan, and the Ukrainian war effort will collapse overnight just like Afghanistan imploded as soon as the US left the country.

The US has to fight multiple fronts against its peer adversaries as well as not-quite peer adversaries. Just recently, there's a coup in Niger with crowds of Nigeriens waving Russian flags cheering the coup leaders. While Western MSM underreport the average Nigeriens' heartfelt desire to kick out the French and overexaggerate Russia's involvement per usual, an anti-France alliance is forming in the Sahel, and Putin has launched a charm offensive courting African leaders. This is the formation of another front between the West and Russia, and the US will funnel resources away from Ukraine and towards various jihadist and separatist groups like Boko Haram in order to destabilize West Africa.

Ukraine isn't so exceptional that the US will be willing to abandon a front and lose say Taiwan for the sake of Ukraine. And from MSM reporting about the failed counteroffensive, we're close to the "US cutting their loses and leaving their allies out to dry while Hexbears repeat that quote from Kissinger" stage.
