Yep. The liekly difference is that it may work between democratic countries that don't want to wage war between each other, but likely not with militaristic dictatorship, that wants to wage a war (since lowering the standards of living for the subjects is mostly a problem only in democracies, because people elect the leadership). Relationships go both ways, and so far it looks like neither side has a reason to sever them quickly, despite the war (Russia wants the money, democratic governments want to be elected next time). Severing is very gradual allowing for gradual adjustment on both sides. No huge shock. No huge deterrent. And I don't get the purpose of the interdependency in case of direct attack either, with the attacker being the supplier. Attacking country cutting you off from significant portion of fossil fuels before the attack, will not make your defense any easier.
