Tell that to the members of the Kosciuszko Squadron, or the Polish soldiers at Monte Cassino.
I did not say Poles did not contribute greatly to the allied cause. There were many worthy heroes who must be remembered in history. But the examples you cite were as part of the many years later broad and effective allied effort, and not the ineffective and futile resistance in 1939 to Hitlers demands to negotiate.
To put things back in context, this is not a debate about Poland, but a debate about what Pat Buchanan really wrote. Pat wrote an article warning Bush about the silliness of absolute guarantees and Israel about steadfast refusal to negotiate with mortal enemies relying upon foolish guarantees. As an example of how such decisions can turn out, Pat turns to the historical example of Poland remaining intransigent in the face of Nazi irredentist claims and other demands, based on a misappreciation of the actual ineffectiveness of British guarantees. Poland simply ceased to exist for 50 years. No one is saying that the Poles caused anything or that as individuals they were anything less than heroic. But a journalistic hitman (even the WSJ has its moments) misread the article and framed it as Buchanan sympathy for Nazis. A lot of freepers followed the journalistic hit down the pretzel shaped rabbit hole of illogic.
The article is about diplomacy and bargaining in the face of overwhelming force. Nothing else. I praise the heroism demonstrated by the Poles in the war and have deep sympathy for what subsequently transpired. Pat, as a staunch Christian anti-communist, presumably shares that view.
