Any air defence is vulnerable to attack. As soon as it is turned on, it signals its presence.
That is different from whether USA/NATo can establish air superiority. If they can’t, the West will certainly lose in an all out conventional war against Russia - as the Counter-Offensive showed.
That's a serious delusion to have. Russia can't even defeat Ukraine, a nation much smaller than Russia. Russia has no chance against the West. They probably would have trouble against the Texas National Guard.
To put it in perspective, the entire Russian air forces have about the same number of combat planes as the US Marines.
That is a big if, and yes our tactics depend on air superiority and I think as the war has progressed I don’t see that as a problem
Ukraine has caused the Russian Air Force to fight way behind their lines, the Ukrainian attacks on strategic, operational and tactical targets have been effective but not overwhelming, that will not be the case with NATO forces.
Ukranians don’t have B-1s, B-2s, and B-52s that can not only launch devastating long range attacks, but the ability to penetrate and hit targets.
Ukraine does not have F-22s and 35s and their capabilities.
All of these plus other NATO Air Force assets would eliminate Russian air defenses and Air Force capabilities pretty quickly. I am sure there would be loses, remember from gulf 1 that we were told to expect 50% loses of tankers. That never happened because we removed the threat quickly
The elephant in the room is nuclear, then everything goes out the window.
If putin goes nuclear then his dreams of an empire will disappear as well, ain’t people grand
