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.

“Art-Culture-Life”: So beckoned the humble sign. Being a fan of all three, I made my way inside. Art came first in a portico lined with rich, Dalí-esque landscapes; in the craft shop, stocked with mottled straw purses and hand-carved bowls; on restaurant walls, splashed with multihued graffiti. There was culture, yes, in the form of eclectic sounds: a D.J. spinning house music and an open-mic session showcasing poets and singers from Africa to America.

Very little coherent information is currently coming out of the parts of northern Nigeria under a state of emergency. What information is available indicates that activity and violence continue under the cover of the media silence, though it is difficult to judge its degree. In May, cell phones and satellite phones did not operate in the affected areas. Those services are only slowly being restored. Foreign media are almost entirely absent, and domestic media appear to be highly restricted. Foreign diplomats do not travel there.

There has been a lot of talk lately about the relationship between development and trade, just as the United States is stepping up new trade initiatives across the Atlantic and the Pacific. The announcement of the Trade Africa initiative during President Barack Obama’s recent trip to Africa and calls to renew the African Growth and Opportunity Act next year have also put the benefits of trade with sub-Saharan Africa front and center, which holds 7 out of the fastest 10 growing economies.

It is commonly known that monetary remittances, the funds that foreigners working abroad send back to their origin countries, make up an important part of many developing nations’ economies. Less commented on, however, are social remittances, or the influence migrants exert on their home countries’ politics. One of the most important mechanisms for social remittances is the absentee ballot. According to the International Institute for Democracy and Electoral Assistance, 115 countries or territories now grant voting rights to their citizens living abroad.

When successful entrepreneurs come together, the ideas that emerge are nothing short of amazing. And when those entrepreneurs are also women who have fought gender bias and other challenges, the ideas have the potential to change the face of commerce for a continent. This week, we welcomed to Washington small and medium-sized business owners from 27 countries in Africa who spent the last two weeks meeting with U.S. entrepreneurs and CEOs in places like Los Angeles, Chicago, Seattle, and Albuquerque, as part of the African Women’s Entrepreneurship Program (AWEP).

In the heat of the afternoon, especially this past month of Ramadan, downtown Tunis plays dead. Offices and shops close at 2 p.m. and life is suspended as everyone, parched and hungry, waits for sunset and the breaking of the fast. On a side street behind the Interior Ministry, the only movement is the occasional rumble of a tram, the only sound the trill of its bell warning pedestrians to step off the tracks.

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.
