You have been wrong about literally everything in regard to this war. You have been doing all the bleating, especially before the war started, when you claimed that it would never happen.
They have been trying for months and getting nowhere. The only realistic way into Slovyansk is south through Izium and guess what? The same river is blocking them there too. As I already mentioned in my previous post, the Russians at this point are incapable of making bridgeheads to get across the river. Every time they do, they get massacred by the Ukrainians.
So your proposed solution is facing the exact same issue. Stuck on the wrong side of the river. Nice try though.
