"1529--When Genghis Khan And His Dinosaur Legions Invaded."

It's the Day's Day of Days!  Because Mars Attacks!

Actually, Suleiman did have Christian allies.  They were called 'Protestants'.  Martin Luther even stated that it'd be better to be ruled by a competant Muslim than an incompetant Christian.  In fact, the son of the man who ruled Vienna would go on to launch an invasion of Protestant England--Philip II of Spain.  I don't think Muir would consider Spanish rule, with its Inquisition, Cortes-smashing absolutism, and government censorship any sort of ideal--indeed I imagine he takes a great deal of pleasure in descending from a nation that defied it, and helped another to do so.

Which is not to say that Suleiman was "the good guy" and Charles V was "the bad guy".  But what Muir--and the hordes of ignorant racist twits who love to scream about the "Gates of Vienna" whose cue he's following--refuse to recognize is that this was a battle between two Renaissance states that we would find very alien to our sensibilities, fighting over things we would consider ridiculous.  (Like who was the real King of Hungary, John I or Ferdinand I.  And if you're wondering, the answer they agreed on was 'yes'.)  And despite their rhetoric--both states respected one another, traded with one another, and kept in diplomatic contact with one another. Muir is using a past that does not exist to comment on a present that doesn't either.
