It's incredibly sparse, though.

Mongolia barely has a higher pop than Wales (3,500,000 vs 3,200,000) but is... considerably larger (1,500,000KM^2^ vs 20,000KM^2^), with nearly half of the population live in the capital city.

Even if NATO flipped the government, there's not much that they could do. The armed forces are minuscule (35,000 active service, most of the country is on the draft) and culturally/politically the civilian population is far too under the Russian sphere to ever accept that hypothetical govt for long.

I guess it could be a tactic to further tie up Russian forces on multiple fronts, but I feel as though if that were an option it would have happened by now.
