Russia and Ukraine

[Thumpalumpacus]

As for pincer movements to cut Ukraine in half-  While it's fun to posit that the russian forces could effectively operate 90-100 miles from a railhead, mere reality on the ground doesn't paint that picture.  They've been incapable of effectively operating beyond 30 miles in any engagement.  All of which is to say..that if the russian forces were five times more competent than they are..then..they could attempt such a pincer..and then it would be a more even engagement.  

As it stands, clown army being executed more than engaged in combat.  I'm sure, just absolutely certain, that the surviving troops of these utterly defeated regiments are going to do very well on the eastern front - where there's been a trench stall for almost a decade, and ukraine had preemptively massed it's best and most well equipped forces.  Meanwhile, the first batch of ukrainian volunteers is set to complete training and enter the battlefield.

Executing a mass attack with what is essentially a scratch force of defeated units hastily reorganized, lacking proper air support ... I'm not buying great odds of success, especially now that the scope of the atrocities is clear and every Ukrainian civilian knows what defeat would mean.

The Ukrainians were literally not allowing black people to evacuate, and they have a whole military unit that are literally nazis.

That was actually the Poles who were turning away African and Asian exchange students and workers at the border, from my readings, rather than Ukraine refusing to let them leave the country.
