According to the folks over at StrategyPage, Russia can only count on some 100K soldiers among its regular army (contract volunteers) and various military and internal troops' spetsnaz units.

This would mean that in any purely conventional scenario, the US could deploy more effective ground forces on an expeditionary basis against the Russians than the latter could deploy on a defensive basis.

Basically, without nuclear weapons, Russia could not halt a determined peer adversary such as NATO or China. Thoughts?
