The title above is by Paul Schwennesen a "military affairs analyst and environmental historian", writing in Reason magazine (Reason.com). It is worth reading. It is not about the advantages of military resources or the advantage of foreign support for either Russia or Ukraine.
The article is built on anecdotes about the resilience, cohesion, and fighting spirit of the Ukrainian people and the Ukrainian military, all lacking on the side of the Russians even when they are defending their own territory as they are today in the Russian region of Kursk.
In the early days of the war, no one believed that Ukraine could last more than three days, did no one expected that Ukraine over the first months of conflict would push the Russians back from most of the territory they occupied? Did anyone believe that Ukraine could invade Russia as they have done in Kursk?
What accounts for it, when the Ukrainians, especially in the early days of the Russian invasion, lacked Russia's arms and manpower. Certainly, the Russians made mistakes that have cost them dearly, but if the Ukrainians had acted as expected they would still have been overwhelmed by Russia's military superiority.
Ukrainian resolve, Paul Schwennesen writes, made the difference and will determine the outcome of the war.
Schwennesen concludes, "The moral scales have now firmly settled on the side of the Ukrainian defenders, and it is far likelier that Russia itself splinters into its constituent republics than that Ukraine falls to its erstwhile invaders."
