Even if theism is a failure, it's still superior to atheism

The Mongols were no different than any other warlike people in those days, except for they were more effective at conquest.  And in some ways they were more restrained than other people, if you surrendered for example the would let you live and only impose a relatively minor tax.  Contrast that with the behaviour of those who lead the first crusade or the Cathar ceusade.

And the Mongol conquest of Persia and the Central Asian steppe was precipitated by the sultan of Khwarezm murdering an embassy Chinngis sent without any provocation.

Among certain historians, there has been a recent movement to rehabilitate the Mongols, which is the view that you are presenting (defending?); in my book, they were/are mass murderers, even if they lived in an era of mass murder.

But what you are doing is trying to paint them as worse than other conquerors of their time, a view only ever propagated by racist European and European descended propogandists.
