Edit: If you're objecting to HALO insertion as a measure against AA then fine but even describe as a way around AA:
"The technique is used to airdrop supplies, equipment, or personnel at high altitudes, where aircraft can fly above surface-to-air missile (SAM) engagement levels through enemy skies without posing a threat to the transport or load. In the event that anti-aircraft cannons are active near the drop zone, the HALO technique also minimizes the parachutist's exposure to flak...
... The combination of high downward speed, minimal forward airspeed, and the use of only small amounts of metal helps to defeat radar and reduces the amount of time a parachute might be visible to ground observers, enabling a stealthy insertion."
How many helicopters can Russia sustain to lose? They've lost several over the last few weeks.
Supply routes have be successfully attacked by Ukraine with estimates of slowing logistics by 50% in certain areas.
And again how many AA batteries can they sustain to lose?
Meanwhile Ukraine has made slow but steady advances forward gaining ground.
Where's Russia changing the direction? Is that by terrorizing civilian targets (your bombing campaign) and blowing up hydroelectric dams? So essentially they're just using the tactics of terrorists.
Yet they still can't freely fly over Ukraine because they still lack control over the skies.
When's Russia regaining the momentum in their favor? Last week one of their best units tried to storm Moscow and hang their top military leaders.
AND now Russia is more weakened to a full confrontation with NATO than they were before starting their war in Ukraine. So all the more likely to lose air superiority to NATO+allies.
How is Russia establishing air superiority over Ukraine now? Or is going to change the tempo of the war into their favor?
How does this pertain to them denying NATO+allies from probably eventually attaining air superiority in a hypothetical full conflict?
What happens when the enemy has exhausted it's supply of AA ammo?
Or lost use of its radar?
It doesn't need to be singularly successful since it's part of a collective of redundant systems[2]. Air isn't working then increase missile strikes, missiles can't attain good effect on target then increase covert operations with local insurgencies, etc.
That's just some of the possible angles of attack. There's leaving out things like drones and cyber attacks that would also be employed to some effect.
Eventually the enemy loses the ability to fight since it's critical points are weakened to such a point it can no longer wage an effective resistance.
Another example: why attack heavily defended artillery positions when you can blow up the logistical route and starve them of rounds to attack with?

Then jets like the F-22[3] would be used to establish command of the airspace.
