What a complete load of crap - I grew up in a Polish neighborhood and knew many Polish vets from WW II - some fought in the Warsaw uprising - every one of them despised the Ukrainians as their enemies - not one of those WW II vets ever thought of the Ukrainians as their friends or allies.
My dad fought Germans in WWII, being attacked by Luftwaffe planes, about 40 years later I was parachuting out of Luftwaffe planes and earning my Fallschirmjäger wings and considered the Germans among our top allies.
