Ok, what if NATO collectively (or at least the affected members) decided to destroy the pipeline in a show of resolution?

Let's say secret negotiations are ongoing (it would be surprising if they weren't) with Russia regarding a winter ceasefire. Russia annexes the occupied regions to force the hand and be in a better position, then offers gas in exchange of no NATO military help during the ceasefire.

NATO rejects the offer and blows the pipeline to show it is off the table.
