But they still remember the betrayal by FDR when he gave Poland to Stalin
Also, the USA was instrumental in and played a huge role in freeing Poland from the USSR, but it did not "liberate Poland" -- the Poles did it themselves starting first with the Solidarity movement.
Stalin made the same mistake that the Tsars made -- trying to incorporate Poland into a Russian alliance -- that action has twice disintegrated Russian empires. Why? Well, Stalin said it himself -- putting communism on Poland was like putting a saddle on a cow
Poland never fell for the pan-Slavic myth that the Muscowites peddled (well, they did like pan-Slavism, but as long as it was lead by Poland or anyone but Moscow) and it considers itself part of the West by virtue of its Catholic culture
Poland would never be digested by Russia -- it would cause Russia severe indigestion.
But this time they don't trust their "allies" to fully live up to their promises....
America and Reagan liberated Poland, Poland do not do it themselves, but their pressure, along with Thatcher and NATO and all the other forces that Reagan assisted and showed light to and support for, all helped us.
No America then no opposition to continued Russian conquest and control, no Reagan, and Poland would still be under Russia.
