The headline is fine, but why are there Polish soldiers in the photo? Author, look closely. The photo shows several men in traditional Polish military uniforms.
I don’t have an eye for uniforms, so I can’t comment on whether they’re Polish soldiers. I got it from here.

The postwar Polish government was a creature of the Soviets, though, and quite nakedly so.
Unfortunately, during the info war, propaganda flows both ways. There were deportations in Stalin era (not just by the Soviets, but also Polish, Germans, Turks, Greeks etc), but calling it an ethnic cleansing when just a few years prior an actual ethnic cleansing of Jews was taking place, is kind of a stretch. This particular photo is probably from the population exchange between the Polish and the Soviet Ukraine.
