I don’t know that I agree about air dominance. Ukraine has been bombarded by glide bombs, and Russia is getting a lot of value out of artillery and air support to soften positions before rolling in their conscripts.
I’m not saying that invading or counterattacking is definitely a mistake. I’m worried that those troops would be better utilized at the front. Either way we will see how this plays out as Russia repositions troops over the next week or so. Hopefully Ukraine can hold the line and keep from getting encircled
