Germany and France are both gonna vote no. Ukraine isn an active war zone, one of the requirements is to not have any unresolved military conflicts to join. I will say though, the pipeline blowing up makes things tricky and NATO might form like voltron if it was Russia, but there are certain NATO countries that stand more to gain from that pipeline sabotage than Russia (Lithuania, Latvia, Poland etc.)
If NATO intervenes in Ukraine, Russia has three options. One would be surrender (smartest option) but then that means Putin and his people either get arrested and sent to the Hague or they all fall out of windows mysteriously. The second option would be the tactical nuke (stupidest option) which is a risk that either scares NATO off or destroys the planet.
The last option would be to sell their soul to China, and use their massive production capabilites like they used the USA in WW2 for a lend lease program. That and to continue buying drones from Iran, but while that MIGHT prolong the war a bit longer, they would lose face as a great power and be relegated to Mase in his own videos status eternally
I dont see a good way out of this
