Things Could Go Battlefield Nuclear If Ukraine Counter Attacks While Russia Is Retreating To Dig In In The East.

If Ukraine tries to keep Russia retreating right out of Ukraine by doing a full assault on Donbas sweeping south to Crimea then Russia would pull out the battlefield nukes and now you really have WWIII spreading outside Ukraine.

China would probably pre-emptively take Taiwan at that moment before the US could get there and establish a beach head.
