Obama's special advisor on the Middle East, Dennis Ross, announced his resignation from the Obama administration yesterday only months after Middle East envoy George Mitchell, his predecessor, resigned. He resigned in order to spend more time with his family. The Palestinians considered him to be Israel's representative within the administration, and he was considered a hawk on Iran. When he agreed to join the administration it was initially only for two years, and then he agreed to extend for another year. His resignation can be taken as another signal that the peace process is stalled until after the November 2012 election. It may also signal a disagreement within the Obama administration on how to deal with Iran's nuclear efforts that Ross lost. When he joined the administration it was to concentrate on Iran, rather than on the Israeli-Palestinian peace process. He also gave advice on how to deal with the Arab Spring. Dennis Ross was said to often have been at odds with George Mitchell, whose job Ross had previously filled in the Clinton administration. But he took over for Mitchell, once Mitchell had resigned. Here is an Israeli article on the resignation. And here is a more critical look at his tenure from the National Journal.
