A 'little birdie' passed on to us a leaked George W. Bush and Tony Blair videocast on YouTube which proves that... the two great world leaders are going after the historical generals featured in Firaxis' Civilization IV: Warlords expansion pack, starting with Genghis Khan?

Apparently, Bush's intelligence indicates that Genghis Khan "is on the verge of upgrading his catapults to the devastating 13th Century trebuchet", and the video is just one of a string of related YouTube vids that have just been posted, showing Bush and Blair fretting about a whole bunch of deceased world leaders, from Hannibal (whom George W. is concerned may be related to Hannibal Lecter from Silence Of The Lambs), and Wang Kon (for whom we will save you the punchline!)

So, whether 'viral marketing' or enthusiastic fan video (we bet on the former, thanks to an ESRB rating at the start of the spots, and some pretty darn good voice impersonators), these are well worth pointing and poking at - even if we had no idea Sid Meier was so political!
