Uh, yeah, Russia already describes the current war in Ukraine as against “the collective West”.
> they don't need to threaten that at all,
Whether or not you think Russia needs to issue war threats to Western states, rhey’ve been doing it a lot inn last year.
> if it got to that point they might as well just nuke Berli
The point of a threat is to dissaude an opponent before it becomes necessary to execute on. Yhe threat. So other attacks that they might do if the threat fails don’t really effect whether the threT might be seen as useful. Also, Russia has made implicit nuclear thrrats to Germany, most, recently over the decisions to send MBTs to Ukraine.
