I think if we'd had a history of making statements of military intent against Russia or Germany pre WW2 things could've gone very very bad for us and destroyed the nascent independent state, and it isn't a certainty that this current invasion doesn't spiral into something far worse across the continent
That's my concern for these kinds of statements, coupled with the fact that they're already being armed by the USA far better and far faster than we could ever remotely match so it isn't like they'd be some consequential factor in the war if we sent a few javelins
We were gone if the Nazis won the war despite the bizarre vibes from FF at the time. Also the Soviets were more interested in managing their own sprawl than us. You're overthinking the volume of our voice.
