The Arab world is 'electing' Islamic fundmentalist governments everywhere, Syria is burning in a civil war with over 5000 now dead, Hamas and its allies in Gaza are launching rockets now every day against Israel without fear of retribution and Hezbollah has started to do the same from Lebanon while also attacking UNIFIL troops there. Iran is threatening to close the straits of Hormuz and in addition to threatening Israel with annihiliation is also threatening its other neighbours; Egpyt, where mobs with government approval destroyed the Israeli embassy, is now allowing Hamas and Al Quaeda to operate in the Sinai (meaning that the road in Israel to Eilat is effectively closed); and of course the Palestinian Authority - which has refused all offers to return to negotations and is honouring terrorist murderers with all kinds of money and prizes while ratcheting up its hateful Israel deligitimization campaign throughout the UN and UNESCO.
None of that is an 'onstacle to peace'. But Israel planning to build 40 new homes? This has brought world outrage and official UN condemnation:
UN: 40 new Efrat homes prejudice the peace process
