That I telling long time ago.
Good relations between Poles and Ukrainians, among all Slavs (not only Slavs but, I here speak of Slavs), after all, but, not on the account of truth. Poland as serious state and Poles as serious people, must define what happened and in which territory Poles don`t exist anymore because they were exterminated. Same process must be concluded between today`s Serbia and Croatia- because Croatia wouldn`t exist as such if 700.000 Serbs were not exterminated in WWII.
I look forward to the future when will all Slavs settle their score with Germany, too. Meaning, on whatever territory Slavs were exterminated, German state can`t exist but rather territory must gain Independence if people there want it, or territory must be attached to neighboring Slavic country. Here I point on territories where we have clear documented basis (so I don`t speak of antiquity) of destruction of Slavic pre-Christian states (but states with border on the map), in early middle ages, in what is now Germany.
and of course both are united against the common threat: the murderous Putin's evil empire, Russia.
Why you as Anglo always point on Russia? Do you enjoy in hate among Poles and Russians? Is that it? You see Russia everywhere. Polish-Ukrainian relations are one thing, Polish-Russian relations is the other thing. It also means that Polish-Ukrainian relations aren`t solely problematic. They had some positive moments, too. Same is with Polish-Russian relations. What is sin would be named as such. What is good would be also named. Antagonisms among Slavs aren`t eternal category. Actually, often were result of workings of foreigners.
