In the latest worrisome saber-rattling sparked by the US-led proxy war in Ukraine, Russia announced it's revising its doctrine on the use of nuclear weapons, saying a change has been necessitated by "escalation" initiated by the country's Western adversaries. 

Russian Deputy Foreign Minister Sergey Ryabkov told TASS that the update was precipitated by an analysis of  "recent conflicts" including "Western adversaries' escalation course" in the Ukraine war. The revision is "in the advanced stage," but Ryabkov said it was too early to project when it would be completed, given "we are talking about the most important aspect of our national security." While there's been no indication of the specifics, any revision seems certain to lower the threshold for nuclear weapon use -- and increase the potential for a global conflagration.
