What Western nations doubt is that Russia would actually attack them or use nukes

Russia launched everything but the nuke. That should be the takeaway.

Yes, everyone knows they have nuclear weapons, chemical weapons, all that fun shit, everyone knows they have ICBMs.

They’ve implied verbally that there could be scenarios in which they’d feel justified with using a nuclear weapon, but they literally just launched everything but the nuke. It’s a pretty major escalation.

I’m also not here to speculate as to whether it’s a hollow threat, I’m just pointing out that launching an ICBM is a really big deal
