CTL > Wrong again! The USSR invaded Poland in September 1939 joining on the side of the Nazis
Indeed, the commie history counts USSR’s entry into WW2 as 1941, ignoring their occupation of Poland and attempted occupation of Finland in 1939, and of Baltic countries in 1940, I may be missing some, like Bessarabia. Visiting Uman even before 1939 probably was not well advised, unless you were a pro-commie world-famous writer or journo, ready to tell the world how great USSR is.
On a more somber note, tefilos in Uman somehow were not helpful throughout 20th century – from WW1 to anarchists to Whites to Reds to Holodomor to WW2 … They started helping in 1990s but the region is back downhills…
