Well consider that UKR is doing approximately that with its army now. Nothing the US foot soldiers could do but add to the momentum UKR forces have attained. USA could help with Anti Air defence and longer range missiles but that's about it. There is no silver bullit given UKR's stellar performance--one is not needed. Must remember how dispersed the troops are/ They are not like penguins floating on an island. So a one stroke plan is impractical.
It won't be one stroke, it will be over several days.
- Stealth fighters target air defence systems and Russian jets. Knock out every single thing that could threaten a NATO jet. This will take a few days by itself- Russia has a lot of air defence.
- The Black Sea Fleet will also need to be knocked out, either by stealth fighters or by submarines. Those things are basically floating air defence bubbles.
- Once air superiority is achieved, start dismantling the Russian army in Ukraine with conventional aircraft flying at high altitude (to avoid MANPADs). Trains, supply depots, command points, artillery, tanks, IFVs, supply trucks - bomb them all.
They won't be able to win the war solely from the air, but if the Russian army is reduced to a bunch of infantry with no supply lines and no C&C, the job for Ukraine is basically one giant mopping up exercise.
