I can't presume to say what anyone should be doing but I would expect some oil companies to be lining up, ready to get in there before the existing lines freeze up in the permafrost should the pumps stop.

In the context of 'sudden collapse of Russia' in general? Probably just make sure back channels to whoever has control/custody of Russia's nukes are available. The west's primary goal should be ensuring the safety, security, and non-use of Russia's nuclear (and whatever WMD) arsenal in the event of collapse.

Beyond that, I don't think there's a lot the west can actually do? Attaching western support to any one would probably completely de-legitimize them as an immediate post collapse player.

I would imagine mainly containment; make sure the collapse of Russia stays in Russia and that you don't end up with black market tanks in Poland or a warlord seizing mines in Kazakhstan.

>black market tanks in Poland

Why would that be a problem? plenty of museums to take them in, might get handy like last year when we sent >300 modernized tanks to UA.

> or a warlord seizing mines in Kazakhstan.

Kazakhstan is independent for over 30 years now

Same thing they did when the USSR collapsed. Basically, make sure the nukes don't end up in the hands of a bigger monster or they're not sold to rogue states/organizations.
