What do the natural gas that began to flow to our homes from the Tamar reservoir, US President Barack Obama’s visit to Israel, and the expected rapprochement between Israel and Turkey have in common? Answer: The new public diplomacy.

U.S. President Barack Obama’s speech in Jerusalem this week was without question the strongest ever made by a senior American politician on the Israeli-Palestinian conflict. It was plainly designed to speak directly to the Israeli and Palestinian peoples over the heads of their political leaderships. It was an exercise in public diplomacy par excellence, intended to change the tone and atmosphere, and public perceptions of Obama himself

For all the drama of President Obama's stirring speech Thursday in Jerusalem, the most encouraging thing about it may have been the applause from the audience. "Remarks of President Obama to the People of Israel," the White House called the speech -- and, like President Reagan, Obama went soaring over the heads of officials, elites, and pundits, directly to Israel's citizenry. In that may lie the nub of a second-term approach to Israeli-Palestinian peacemaking that could prove more fruitful than the frustrations of the first.

Obama was accompanied on a leisurely tour through Petra's steep red-rock formations by a University of Jordan tourism professor, with all other visitors kept well away -- except for a few stray cats. Soon after his stroll through arid the landscape, renowned for its colorful interplay of light and shadow, the president is due to return to Washington, DC.

President Barack Obama’s relationship with Israeli Prime Minister Benjamin Netanyahu has never been warm. So while visiting Israel, Obama did not limit himself to the standard rhetorical niceties. He went over the heads of politicians and appealed directly to the Israeli public, especially the young, to make his case for a more flexible approach to negotiating with Palestinians.

President Barack Obama arrived in refugee-flooded Jordan on Friday after scoring a diplomatic coup just before leaving Israel when Prime Minister Benjamin Netanyahu apologized to Turkey for a 2010 commando raid that killed nine activists on a Turkish vessel in a Gaza-bound flotilla

Obama will not carry with him a detailed proposal for how Israelis and Palestinians might resume talks, such as the one he offered in 2010. He instead plans a listening tour in Jerusalem and in Ramallah to solicit views on what the two sides want and to explore what may be possible.

Coming less than a week before Mr. Obama departs for his first trip as president to Israel, the comments Thursday set the stage for an airing of the two timelines for any eventual military action against Iran’s nuclear installations that separate the White House from Israeli Prime Minister Benjamin Netanyahu.
