Did all the Japanese get killed after they surrendered? Did all Germans? If they had surrendered earlier less of them would have died. The same goes for Nazi Ukraine. Their defeat is inevitable, and prolonging the inevitable only adds to the suffering...and to the list of war crimes that they will be charged with by Russia's tribunals afterwards. The West's "support" is literally destroying Ukraine and they have all admitted that they have no problem with this, in fact they profit from it.

The West is happy to "fight to the last Ukrainian" to hurt Russia, the Banderite Nazis are happy to die (and force their less fanatical compatriots to do so as well) for the West so long as it enables their genocidal urges, meanwhile the only ones who actually care about the Ukrainian people and have gone out of their way to try and save them from the Western imperialists and from themselves are the Russians.

It's actually really sad that there isn't a single country on the planet that cares about Ukraine except Russia (and maybe Belarus). To the West they're just a tool, useful idiot cannon fodder, to the rest of the world they're a tragic cautionary tale about what happens when you let the lunatics take over the asylum, which is what happened on the Maidan in 2014. If you really cared about Ukraine you too would want the flow of weapons and money to them to stop, because the longer this goes on the worse it will be for them.
