Taking on the extreme derpitude of #neocongE is no easy task.
Most articles about the war like the one from the NYT's are written from the perspective of the U.S. military experience against Toyota pick-ups, clay huts and a few RPG's. Not billions of dollars of high tech weaponry, massive first world surveillance including space based assets, and last by not least, the U.S./NATO propaganda machine (which taps the usual suspects into writing cheerleading articles, that for example convince people that the Afghan military was going to stop the Taliban).
The Ukrainians have burned through decades worth of production of weapons platforms and munitions supplies in a few short months and are still giving up territory and still losing men and equipment by the rail car full. Our military leaders have completely miscalculated the level of munitions and supplies needed to fight the Russian (or similar) even in a limited war. Trillions of dollars spent over the last 20 plus years, and they've been completely sucked into the group think of what it takes to fight 3rd world people living on rocks and in clay huts.
