No, I'm not talking about America but Kafiristan - yes, believe it or not, it's a real place. And ironically it's in Afghanistan.
Kafiristan or Kafirstan ("Land of the Infidel" in Persian) was a historic name of Nurestan (Nuristan), a province in the Hindukush region of Afghanistan. This historic region lies on, and mainly comprises, basins of the rivers Alingar, Pech (Kamah), Landai Sin, and Kunar, and the intervening mountain ranges. It is bounded by the main range of the Hindukush on the north, the Pakistani border on the east, the Kunar Valley in the south, and the Alishang River in the west.
Kafiristan takes its name from the inhabitants, the Kafirs, a fiercely independent people with distinctive culture, language and religion. In 1896 the country was conquered and forcibly converted to Islam by the Emir Abdur Rahman Khan, who renamed the people as Nuristani ("Enlightened Ones" in Persian) and the land as Nuristan ("Land of the Enlightened").
While the etymology is contested by some it was used and understood as 'The Land of the Infidel" by the neighboring Muslims.
I just think that jblogosphere tends to get a bit narrow-sighted when the only considered possibilities are Judaism (somewhere along the spectrum) or non-Judaism. From the Muslim perspective (one fifth of the planet, mind you) we're all kaffirs anyway. It seems to put things in some perspective.
