Earlier quoted context omitted.
> only the US & allied governments are actually actively promoting the idea of going to war. It's incredibly costly to park 150,000 troops and armor in a position to invade. But your issue is with the governments saying "excuse me, why does it look like you're positioning your troops for an invasion?" OK.
Don't overestimate the cost. If the units weren't there, they'd be doing large scale exercises and maneuvers, which can be even more costly. From the perspective of the Russian army, stationing a medium-sized force within their own borders is not going to be that expensive. Also, the corresponding increase in gas prices is going to counteract that perhaps even completely.
Also from what I understand a lot of these Russian troops are actually in Belarus as well.
