Iberico ham comes from Black Iberian Pigs. It doesn't matter if that Black Iberian Pig is in Arkansas or Spain, it will still be a Black Iberian Pig, you can't take a Danish Protest Pig, ship him off to the Iberian peninsula, slaughter him and call him a Jamón ibérico. Parma ham by contrast requires no specific pig or boar, it is dry cured ham from Parma. If you are going to use analogies, do know something about it.
