Richard Falk is an international law and international relations scholar who taught at Princeton University for 40 years. In 2008 he was also appointed by the UN to serve a six-year term as the Special Rapporteur on Palestinian human rights.
He has written an article on Yemen, which is worth reading. He writes, "There are two obvious moves, neither ideal, but with the modest goal of a first step in creating a new political order: first, negotiate a ceasefire that includes an end to the Saudi intervention; secondly, establish a more credible revival of the National Dialogue Conference that two years ago made a failed attempt at Gulf initiative in Sanaa to find a power-sharing arrangement. It did not help matters then that two successive Houthi representatives at the diplomatic discussions were assassinated on their way to participate. What is needed is establishing a political transition sensitive both to the north/south split and the strength of Yemeni tribes coupled with massive economic assistance from outside, as well as the establishment of a UN peacekeeping presence tasked with implementation and the termination of all forms of external armed intervention. Nothing less has any chance of working."
