I know the comment is largely ironic, but seriously Putin is not a leader we would want in this country or anywhere else.
Just to take one example of how the former KGB head has abused his power, he most likely had a part to play in the death of the dissident Alexander Litvinenko (an assassination that was designed to prevent even more damning information from being revealed). I highly recommend this book: http://www.amazon.com/Death-Dissident-Poisoning-Alexander-Litvinenko/dp/1416551654
