The fundamental disagreement that exists in this thread is that I don't accept the premise that "all they have to do is hold on and Putin will quit" that many of your running buddies have adopted.

Fair enough. Although there's lots and lots of historical examples of where a country with a smaller military has managed to get a country with a larger military to withdraw.

But even if you don't accept the premise that this might happen in this situation, you should stop telling people that they disagree with you that Ukraine's military is unable to physically dislodge the Russian military from Ukrainian territory. Nobody disagrees with you on that, and when you keep claiming that they do it illustrates that you either don't understand or are choosing to ignore what people are actually saying.

Everyone agrees that Ukraine's military cannot physically dislodge the Russian military. We disagree on whether that precludes Ukrainian victory.
