Anyone interested in a Ukrainian backdoor entry into NATO?
Zelenskyy cedes the western half of Ukraine to Poland (west of the Dnieper River, which includes current hot spots Kiev, Kherson, and Nikolaev. It is also 95% ethnic Ukrainians, as opposed to East of the Dnieper which is 95% Russian. I'm not certain of the exact numbers... but something along those lines...).
Poland admits the union of western Ukraine officially into Polish control. Poland/(western Ukraine) declares war on Russian troops West of the Dnieper River.
Putin sues for a peace deal.
PS: Historical precedent - The Polish-Lithuanian Commonwealth in the 16th century included Poland, Lithuania, and western Ukraine.
