Until 1956 they didn't even bother to learn Polish. It was their Polish flunkeys who had to speak Russian. The rulers of Poland were NKVD general Ivan Serov, Minister of Defence of the People's Republic of Poland was Russian General of Polish origin Konstantin Rokossovski - there were jokes circulating about his "Polish" language.
In later years after 1956, sure, there were Polish administrators of the country, but they wouldn't have stayed in the saddle for a week were it not for Russian armies stationed all over Poland in strategic places.
Russia and Poland can together form an alliance of moral uprightness against the tendency of the west to deteriorate into secularist immorality.
Oh please. Poland and Russia? Catholic Poland and generally atheist with a few spots of nationalist Orthodoxy Russia? Against what? West? Bwahahaha!
True but on the other hand she was nice until you came with that #**#.
