Ever since Ariel Sharon sank into a coma eight years ago, many have wondered whether he would have taken the peace process with the Palestinians any further after the 2005 withdrawal from Gaza. A series of cables from the U.S. Embassy in Tel Aviv to the State Department that were leaked to Wikileaks show that in fact, even before the Gaza withdrawal, Sharon was planning his next big diplomatic move.

What’s a U.S. ambassador to do when he wants to get his message out in a country that enjoys making America look bad, has little patience for Western values and tightly controls the media? Call him @McFaul, the tweeting ambassador. For Ambassador Michael McFaul, the unfiltered communication offered by social media means he can tweet U.S. policy, blog it and post it on Facebook, an alternative to the mostly hostile traditional media here.

Iran and six world powers reached an agreement Sunday on how to implement a short-term deal that was struck in November and gives the parties a six-month time frame, beginning on Jan. 20, in which to conclude a long-term agreement about Iran’s nuclear program. The Islamic Republic will open its nuclear program to daily inspection by international experts, starting the clock on the six-month deadline for a final nuclear agreement.

In its last-ditch attempt to get moderate Syrian opposition groups to the negotiating table, the Obama administration faces the prospect that a no-show wouldn't be such a bad thing. With less than two weeks to go before a long-planned peace conference in Switzerland, the main Western-backed moderate political group seeking to oust Syrian President Bashar Assad has still not decided if it will attend. It's the latest frustration for the U.S. and allies who have spent the last 18 months trying to negotiate a transition of power from Assad to a new, representative government.

Almost as soon as a Russian court convicted activist Alexei Navalny of embezzlement, on highly dubious grounds, in July 2013, U.S. Ambassador Michael McFaul tweeted his disappointment at the “apparent political motivations in this trial.” Within minutes that comment echoed across Russia’s social media landscape, eventually generating nearly 1,000 retweets and getting picked up by numerous media outlets.

The American Studies Association is a relatively small professional association of scholars, but suddenly it has made an enormous impact on the public discussion of the Israeli-Palestinian conflict. On Dec. 16, the ASA endorsed an “academic boycott” of Israeli universities. It was a victory for what is known as the BDS (boycott, divestment, sanctions) movement, which began in 2005 but has been largely unknown in the United States until now.

Nearly eight months after President Hassan Rouhani's surprise election victory, in which the centrist cleric trounced influential conservative candidates, Iran's hardliners are behaving as if they never lost. Shadowy vigilantes on motorcycles have menaced the family home of a pro-Rouhani filmmaker, and reform-minded journalists are showing up on target lists.

India moved Friday to oust a U.S. diplomat from the American Embassy here, hours after the departure from the United States of an Indian consular officer who was asked to leave after she was indicted on charges of visa fraud. What appeared to be a tit-for-tat action may lead to a calming of the month-long dispute that has roiled U.S.-Indian relations.
