The lesson learned from World War II when the Air Force reviewed daylight and nighttime bombing they found that it made absolutely no difference whatsoever in winning the war very little. The only thing that won the war was a ground invasion. Yes, air flower did soften up the territory, but it did not and could not on its own winter war and that has been true ever since right now..
If you wanna go toe to toe with the Russians in Ukraine and you better find 500,000 troops that you can lose to throw in the fight. And that is a minimum you might need 1 million.
WWII airpower very, very different animal from the airpower of today. Ukrainian troops are on the ground and while they have been slowly losing, have largely held their own. American airpower will only act to push the war in Ukraine’s favor.
