Apples and oranges. Iraqi freedom operations started on March 19. By April 9 Baghdad had surrendered. Fallujah was insurgency, which the Russians will experience in spades.
Absolutely apples and oranges. The Russians, so far, have held back in Kiev. In Baghdad, we didn’t. The Russians have used a lighter touch. Check out the C-130 gunships in action on hapless Iraqi irregulars hiding in the woods on YouTube, the drone attacks, etc.
