I hope they do because it might not be coincidental that we're told Ukraine destroyed Nordstream. Or Zelensky saying such an infrastructure attack would elicit an Ukrainian attack on Russia's oil/gas properties.
In Siberia, Ukrainians and anti-Putin Russian will want to brave the cold more to attack the installations than Russians to defend them. Plus, I bet much of Gazprom's private army was wasted in Ukraine. As I've commented on your stuff before. I believe Ukraine has a surprise up its sleeve. They're lulling Putin into a false sense of local security.
