Yes, I think that the turning point in the Russia/Ukraine war will come quite soon. Russia is transporting by rail many tanks and troops to Belarus. I expect that the next phase of the war will be a massive “no holds barred” invasion of Ukraine from Belarus by Russian troops.
I expect that Ukraine will not stand by and let this happen. I fully expect Ukraine to target Russian military gathering points in Belarus and destroy as many of them outside of Ukrainian soil.
I honestly expect that Russia is aware that this could happen and doesn’t care about collateral damage on either side of the Belarus/Ukraine border.
All bets are off if that happens, but I do wonder if Lukashenko is getting all this Russian reinforcement to shore up his own tenuous hold of power, rather than to invade Ukraine.
If he was minded to do it himself, he could’ve done it when Russia was dominating the combat.
