Accepted by all the world. The 67 borders are accepted by the whole world. However, despite that, all Israel borders are due to change pending on negotiation. Even Nataniahu knows that. Negotiations with the palestinians will probably bring certain changes in borders the westen broder. Israel will remain with some corp of settlements and will probably (inshala) relinquish the areas of the triangle which include arab cities as Umen El Fahen. If negotiations will not be hold, then the "status quo" prevails. Israel will keep settling in land that never belonged to any other country. Palestine never existed and will not exist without negotiations. In sum there is no need to legally annex in order to settle and establish new borders.
