Gotta remember: The Ground Campaign in the gulf war took the US/Coalition an entire month, and that was after a month of sustained air operations and round-the-clock bombings.
Geographically speaking, Iraq is a much smaller country compared with Ukraine by sheer distance.
So, I'm not ready to meme on the Russian military until we start hitting the 1 month mark. It took the most advanced powerful army in the world an entire month to finish off the Iraq Army after bombing them back to the stone age, so I don't see why Russia is a dismal failure of a military for not finishing the war in the span of a week, against a country with a better military and a lot more ground to cover.
