When Israel declared independence it relied heaviliy for legitimacy in its declaration on the 1947 GA plan. By using this as to claim legitimacy, even though, it avoided explicitly accepting the borders, it implicitly did so. You can't rely on the GA vote and then ignore entirely one of its most major provisions. The world and the international court of justice only recognises Israeli sovereignty within th 1967 borders. And Israel itself, of course, with the exception of E. Jerusalem does not claim sovereignty over the West Bank. It could hardly do do, because then it would have to offer the Arabs there Israeli citozenship. The Israeli high court recognised that Israeli is in belligerent occupation of the West Bank. Israel has basically no legitimate claim to any of the West Bank and any pretence that it does is a carefully constructed Zionist myth.
