Negotiating.
I would give Russia that.
But you have to ask yourself why they want to keep Ukraine out of NATO. Is it because they just don’t want NATO encroachment, as they say, or is it because they want to invade Ukraine again in the future.
I would give Russia the “ironclad” agreement not to ask Ukraine into NATO, but they would have to understand and agree that it’s also ironclad that Ukraine will be protected with extreme prejudice if Russia ever invades it. That includes even if Russia claims that Ukraine attacked them.
If Russia can’t agree to those conditions, then they are tipping their hand about buying time for future invasions.
