It is in the interest of the Palestinians to have successful negotiations, and it is against their interests to have failed negotiations. Better to learn the lesson of the second Intifada that erupted following the failed Camp David. So far, Netanyahu does not do "difficult" things, politically. The test for potentially useful talks is if Netanyahu can do something not easy. (I suggested something.) Talking is the easiest, if you tend to lie anyhow. Now, about the freeze being "supported by International law", did you hear about international law concerning "occupied territory"? Can an occupier build in that territory and have his own citizens live there? Why not check the 4th Geneva Convention, Article 49? Try to learn facts, not just ideology.
