@caekislove @BigDuck @sickburnbro NATO has stockpiles, even with the recent donations to Ukraine. They would likely try to fight a conventional war in their conventional way (airpower) until their stockpiles ran dry in a year or two. The brass and politicians seem to be delusional about their warfighting capacity and stockpile size.
Based on both recent and historical behavior, Russia would likely do a slow fighting retreat to wear down NATO, then slowly march forward after NATO is depleted.
