I certainly agree with that. The issue here is a matter of human resources and, again, the will to fight.
We're making a lot of references to World War I in this conversation, which is fascinating. Going back to World War I, Russian forces were advancing successfully in 1917 in a great Kerensky offensive, and then the military simply collapsed. I would not rule that out. That's not a optimistic forecast. I'm simply saying that we have to consider the possibility that the Russian forces in the field, at a certain part, suffering certain levels of casualties, could collapse.
On the Ukrainian side, I agree that they don't have the human resources that Russia has, but the determination really suggests that they will continue. In fact, I would hazard a guess that, even if there was a regime change in Kyiv—a Russian takeover—we would still see a continuing armed resistance movement in Ukraine.
