Magyars

Okay, who knows enough about Hungarian history to answer for me whether the theory that the European powers actually preferred the Ottomans and seriously assisted them in the 1500s for their own selfish reasons has some merit, is just crazy, or is too oversimplified to be asserted? I can read the standard explanations in Wikipedia and tend to accept them, as that outlet is usually okay when they don't have a dog in the fight. Yet even that far back, events have a way of being important in the present, especially in that area of the world, so I hesitate to accept that framing.
