AFAIK there has never been a successful invasion of Afghanistan - Richard Bridge

Down through the centuries there have been many successful invasions of "Afghanistan" (During the Mongal invasion they actually had the entire population killed - can't get more successful than that) It was once given away as a wedding present. Throughout its history up until 1747 it has been passed from one Empire to another and thereafter it has complied with the bidding of Empires until it gained its independence in 1919.
