Yep, although both perspectives can be true at the same time. It’s in the US’s interest for Ukraine to survive as Russia’s punching bag for quite a while. Between sanctions and the gradual depletion of their military might, the longer this drags on, the worse it is for Russia (and better for the west). A swift and decisive victory for either side undermines this objective, although ultimately a victory for Ukraine against a heavily depleted Russia would be the best strategic outcome. This could take some time to play out.
