[QUOTE=cenlaguy]The US has razor-wire fences on the Mexican border, what’s the difference?
The difference is that the international community recognizes the US annexation of Tejas, Nuevo Mexico, Arizona, y California el Norte. Quite a large fraction of the international community, the US included, believe that Isreal’s annexation of the West Bank is still open to negotiation, at the very least.
The Wall does not just separate supposedly Palestinian areas from Isreali areas - it sets in concrete Israel’s definition of what those areas are, which is still in dispute. It also separates Palestinians from hospitals, schools, work, and some case even running water. It is a far different matter than “normal” borders between nations.
