So much for hindu nationalist historiography. Seriously, keep your edge in your pocket and for once see what its all about instead of jumping onto weird ass conspiracy theory bandwagon.
Another good book about Indo-European: "In search of the Indo-European" (http://www.amazon.com/In-Search-Indo-Europeans-J-Mallory/dp/0500276161). A bit heavy on archeology, but interesting nonetheless.
