President Obama, deploring the military-led Egyptian government’s deadly crackdown on Muslim Brotherhood protesters there, said on Thursday that the United States would pull out of scheduled joint military exercises with the Egyptian Army. “While we want to sustain our relationship with Egypt, our traditional cooperation cannot continue as usual while civilians are being killed in the streets,” Mr. Obama said in remarks delivered from his rented vacation home on Martha’s Vineyard.

With U.S.-Russia relations getting increasingly tense, it comes as little surprise that U.S. President Barack Obama postponed his bilateral summit with Russian President Vladimir Putin. Some people wished he would go, if only to send the strongest possible message to Mr. Putin directly about the need to end Russia’s crackdown on human rights. On the other hand, Mr. Obama still has that opportunity when he attends the G20 Summit in St. Petersburg on Sept. 5 and 6.

President Barack Obama is canceling plans to meet with Russian President Vladimir Putin in Moscow next month — a rare diplomatic snub. The move is retribution for Russia's decision to grant temporary asylum to Edward Snowden, who is accused of leaking highly secretive details about National Security Agency surveillance programs. It also reflects growing U.S. frustration with Russia on several issues, including missile defense and human rights.

The young people who led Egypt’s revolution two and a half years ago have been suspicious of the US for the simple reason that it supported former President Hosni Mubarak’s regime for 30 years. From the US perspective, President Barack Obama pivoted quickly from Mubarak to the people; but it did not look that way on Cairo’s streets. When the Muslim Brotherhood’s Mohamed Morsi was elected President in 2012, many Egyptians assumed that America must have supported him, because they could not imagine that the US would accept a result that it did not want.

Among world leaders who engage in twiplomacy - the use of Twitter for diplomatic relations - President Barack Obama wins superlatives for the most followers but Pope Francis is the most influential, according to a new survey by Burson-Marsteller. The global public relations and communications firm found that more than three-quarters of world leaders are on Twitter - the online social networking service that limits messages known as tweets to 140 characters.

A bipartisan group of U.S. Congress members are calling on the Obama administration to issue a strategic document articulating the pivot or “rebalance” to Asia. In a letter dated July 23 and addressed to the new National Security Advisor, Susan Rice, Rep. J. Randy Forbes (R-VA), Rep. Rob Wittman (R-VA), Rep. Colleen Hanabusa (D-HI) and Rep. Madeleine Bordallo (D-GU) applaud the Obama administration on its decision to pivot to Asia, but express concern that America’s actual strategy to the region remains unclear.

Being something of an op-ed writer myself, I consider the nomination of Caroline Kennedy for ambassador to Japan to be a breakthrough. While America's diplomatic envoys have been chosen on the basis of a variety of criteria before -- key posts during the Obama years have, for example, been awarded for reasons ranging from the bundling of donations to the actual giving of their own personal cash -- the Kennedy nomination is perhaps the first time in history that an individual has been nominated for a top ambassadorial post primarily for having written an opinion column.

After having served for three-and-a-half years as the US Ambassador to the Asian Development Bank under presidents Barack Obama and George W Bush, I finally made my first trip to Myanmar last April, to Mandalay, as a private citizen. In early July I returned, landing in Yangon two days before US Independence Day.
