From Scott Ritter, former arms control inspector, writing in RT:
Without projecting Russian intent, the reality is that the Russian military buildup in its western and southern military districts, when combined with the deployment of mobile forces in Belarus, represent a military power projection capability that is not only more than capable of defeating Ukraine, but also NATO forces currently deployed on its eastern flank. The chances of such an all-out conventional-style war may be extremely slim, but there is no doubting who holds the advantage here.
