The Sarmat missile was being developed for a while now, and this is when they were scheduled to be deployed. Their deployment isn't a reaction to anything immediate happening with the war in Ukraine or the conflict between the west and Russia. The tweet appears to make it look like this is Russia is escalating in the context of the current proxy war.
but then we don't have much treaties left to prevent a nuke war. I mean this is important what is happening in Ukraine and in Russia. There is a fire today in St.Petersburg , mostly like a drone attack. This can escalate quickly into something else.
Yeah, the fact that US decided to dismantle all the treaties with Russia is very concerning. In fact, this is one of the main causes for the war in Ukraine since Russia was very concerned about NATO being able to put nukes in Ukraine that could reach Moscow under 10 minutes. The danger of a nuclear holocaust has never been higher than it is now. There is an absolutely insane administration running the US and there's a communication breakdown the like of which we haven't seen even during the height of the cold war. A catastrophic miscalculation by either side is a very real possibility.
