In the course of his address to an audience (including Dick Cheney), marking his receipt of the 2007 Irving Kristol Award from the American Enterprise Institute, Bernard Lewis (as this sentence now reaches neocon saturation point) told this tale (via The Corner) --
when the Barbary Corsairs raided an Irish town called Baltimore in the 17th century, abducting its inhabitants and enslaving them in Algiers, they took away a family named Cheney
This was apparently part of a broader thesis that the West has been at war with Islamism for centuries -- not that Dick Cheney needed the surname similarity for an excuse to ignore what people here and now think of his policies, as opposed to some imagined legacy hundreds of years down the road.
