I could very well be wrong, but in my eyes the war in Ukraine has shown that having a big standing army to swing around isn’t the magic win button it used to be. Ukraine has been resisting far beyond anyone’s realistic expectation despite being massively outnumbered, doing huge amounts of damage to even Russia’s naval assets (in large part due to drone warfare). Russia thought they were just going to roll over the border and plant a flag in to Zelensky’s head, yet they remain embroiled in a bitter war of attrition with a military that is a fraction of their size. For what they assumed was going to be a simple border dispute, they have had to convert their economy to a “total war” footing. The ramifications of them throwing scores of their young male population in to a meatgrinder are going to be felt for generations to come, even if/when they “win” and occupy Ukraine… and they know it, given their penchant for kidnapping children.
