Interesting parallel between two nations, Slovakia and Poland.
Both nations were Slavic and Catholic, yet Hitler left the Slovaks alone, yet persecuted the Poles. Of course the Slovaks, through Father Tiso, were in fact full-blown collaborators with the Nazis.
Hitler may have had such arrangement with the Endecja, but their antisemitism was only matched with their hatred of the Germans.
The Croatian Ustae and Romanian Iron guard were explicitly Catholic Fascist movements allied with the Nazis. On the other hand Franco not only refused to join the Axis, but accepted refugees and refused to let the Germans take Gibraltar. (Some have argued that this is because Franco was a Moranno, but this is meaningless. He was a Catholic.)
