"The success of the Ukrainian military over the past few months, along with the evolution of the Ukrainian state itself toward a more tolerant, more liberal norm, reveals what makes a better army in the modern world. Brains mean more than brawn, and adaptability means more than mindless aggression. Openness to new ideas and new equipment, along with the ability to learn quickly, is far more important than a simple desire to kill.
From the moment the Russian military crossed the border, the Ukrainians have outfought it, revealing it to be inflexible and intellectually vapid. Indeed when confronted with a Ukrainian military that was everything it was not—smart, adaptable, and willing to learn—the Russian army could only fall back on slow, massed firepower. The Battle of the Donbas, the war’s longest engagement, which started in late April and is
still under way, exposed the Russian army at its worst. For months, it directed the bulk of personnel and equipment toward the center of a battle line running approximately from Izyum to Donetsk. Instead of breaking through Ukrainian lines and sending armored forces streaking forward rapidly, as many analysts had predicted, the Russian army opted to make painfully slow, incremental advances, by simply blasting the area directly in front of it. The plan seemed to be to render the area uninhabitable by Ukrainians, which would allow the Russians to advance intermittently into the vacuum. This was heavy-firepower, low-intelligence warfare on a grand scale, which resulted in strategically meaningless advances secured at the cost of unsustainably high Russian casualties. And in recent weeks, the Ukrainians have retaken much of the territory that Russia managed to seize at the start of the battle—and more.
I struggle to think of another case in the past 100 years when a major military power has performed as poorly against an adversary it was heavily favored to defeat. The supposedly second-strongest army in the world, with its martial spirit, brilliant doctrines, and advanced equipment, was thwarted and is now being pushed back by a Ukrainian military whose prospects most outsiders had dismissed before the war."
