On a sunny, crisp November day in 2008, three American civilians joined a platoon of United States soldiers on a foot patrol in Maiwand District, a flat, yellow patch of earth crowned by black-rock mountains in southern Afghanistan. The civilians were part of the Human Terrain System, an ambitious, troubled Army program that sends social scientists into conflict zones to help soldiers understand local culture, politics and economics.

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.

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.

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.

But as the month of Ramadan draws to a close, the main rebel group, MILF, and their followers, said they are praying that the talks, already reportedly at an advanced stage, would result in a final agreement by 2014. That deal could give the area a homeland and a separate government, and would end a conflict that has killed 120,000 people over the past four decades. Negotiations will resume in mid-August in Malaysia after Eid al-Fitr, the celebration of the end of Ramadan.

The U.S. State Department closed its embassies in four sub-Saharan African nations as part of a heightened security alert, days before the 15th anniversary of al-Qaida's bombings of American diplomatic missions in Kenya and Tanzania. Those two embassies targeted in the Aug. 7, 1998, attacks were rebuilt as more heavily fortified structures away from populated areas where they would be less vulnerable to attack.

The United States extended embassy closures by a week in the Middle East and Africa as a precaution on Sunday after an al Qaeda threat that U.S. lawmakers said was the most serious in years. The State Department said 19 U.S. embassies and consulates would be closed through Saturday "out of an abundance of caution" and that a number of them would have been closed anyway for most of the week due to the Eid celebration at the end of the Muslim holy month of Ramadan.
