There is a sense of optimism, cultivated with newly planted rosebushes and flowerbeds, in this capital of the Kurdistan Region of Iraq. For a region that has seen decades of strife, Kurdistan is emerging as "the other Iraq," a place where progress is marked by the opening of new shopping malls and the pouring of concrete at countless construction sites. While other parts of Iraq remain volatile, Kurdistan is furthering both public and private sector investment.

In what a spokeswoman attributed to "an abundance of caution," the State Department decided late last week to close a host of American embassies in Africa and the Middle East, most of them in predominantly Muslim countries, due to concerns about possible terrorist attacks. This decision may have been prudent and was certainly based on extensive, if ambiguous, intelligence, but it should not become the norm.

One of the reasons for the success of social media’s Twitter platform is its ability to summarize a major issue in a few characters, while at the same time providing a link to give more details and credibility to the few words. This week a political activist used some clever research to reveal the hypocrisy and double standards of a politician. Twitter user @bunghan11h juxtaposed two quotes of maverick U.S. Senator John McCain regarding the situation in Egypt.

The second round of US-brokered Mideast peace talks will be held next week, the State Department said Thursday, even as the Palestinians protested new Israeli settlement activity. In a letter to Secretary of State John Kerry, the chief Palestinian negotiator, Saeb Erekat, said Israel's latest settlement announcements were an indication of "Israel's bad faith and lack of seriousness" in the talks.

In case anyone needed reminding, the recent global terror alert illustrates that, 15 years after its first attacks on America, Al Qaeda is thriving. The coup in Egypt and the chaotic aftermath of the Arab awakening is only going to add more militants to this army of radicals. Failed revolutions and failing states are like incubators for the jihadists, a sort of Pandora’s Box of hostility and alienation.

The United States temporarily closed nearly two-dozen embassies and consulates last week, mostly in North Africa and the Middle East, with 19 set to remain closed for the rest of the week. The administration of U.S. President Barack Obama cited intelligence about potential terrorist attacks by al Qaeda in Yemen. On Tuesday, Washington stepped up security precautions in Yemen by ordering all non-emergency embassy personnel to leave the country and urging all U.S. citizens to depart immediately as well. Similar actions were taken by Great Britain.

In Egypt, as in many of the great revolutions of modern history, the people not only overthrew the old order but also remained in the streets of the capital to oversee the creation of a new one. And as was to be expected, the forces of order, notably the army, then sought to send them home. What is unusual about the Egyptian case, however, is that the sit-ins, encampments, and targeted occupations were well organized and had been developed by the Muslim Brotherhood to last in the face of military intervention.

The State Department has closed a total of 19 diplomatic posts in the Middle East, North Africa, and East Africa and has ordered the U.S. Embassy in Yemen evacuated. But what exactly does that mean for U.S. missions and U.S. citizens abroad? To find out, we talked to a current State Department Foreign Service officer who is on detail at the American Foreign Service Association, a union for diplomats.
