I agree with this sentiment. He is getting military aid by the west so he feels emboldened. I think this will change once Ukraine has a series of major defeats in Mauripol,Severodonetsk, Khariv,Sumy, Odessa etc. Kiev is embolden because the only major city they lost was Kherson. But that will change. In a month Kiev’s position will be precarious. Their best bet is drag this out by the spring rains. Once the heavy mud season comes Russian forces will be halted and Ukraine may plan a “spring offensive,” with the Russians forces grounded because of the mud. Wouldn’t be surprised that’s what is planned but it sounds like a fairy tale.
