You know, I consider all these talks about 'borders that aren't borders because they weren't supposed to be borders and thus can't be borders' as not worth a dime. The Palestinian-Israeli border is not unique in that 'the line' wasn't supposed to be a border (as was with the former Soviet republics, former Yugoslavia), was recognized as a border without agreement between the sides (Kosovo/Serbia border), was created as a border out of armistice agreements between the sides (South/North Korean border, Japan/Soviet border). Really, maybe it is enough to kick a death horse?
