Some Republicans and Cuban-American lawmakers are criticizing President Obama for shaking President Raúl Castro’s hand at the memorial service for Nelson Mandela. Their reaction to a gesture of common courtesy should come as no surprise given Washington’s senseless commitment to a failed 50-year policy toward Cuba.

During Tuesday's memorial service for former South African president Nelson Mandela, as tens of thousands gathered in the FNB stadium in Johannesburg and millions more watched on television, an entirely different story emerged: the ten-second interaction between U.S. President Barack Obama and Cuban president Raul Castro.

We've all seen selfies taken in questionable places. During a school lockdown. In front of a man attempting suicide. At Auschwitz. Now, some people are adding President Obama to the list of people with poor selfie judgment after the leader of the free world posed with British Prime Minister David Cameron and Danish Prime Minister Helle Thorning-Schmidt at Nelson Mandela’s memorial service Tuesday in South Africa.

Fifty-three heads of state and government have so far confirmed attendance at upcoming memorial events for peace icon Nelson Mandela, South African Foreign Minister Maite Nkoana-Mashabane said Sunday. The dignitaries will include U.S. President Barack Obama, along with three former American presidents, Brazilian leader Dilma Rousseff, French President Francois Hollande and British Prime Minister David Cameron.

Cuban Jewish leaders say they have visited a U.S. government subcontractor imprisoned on the island. A statement from Beth Shalom Temple says they met with Alan Gross, of Maryland, on Thursday. The visit came two days after Gross marked four years in custody, and on the last day of Hanukkah.

What Jimmy Carter began, Barack Obama is ending. Washington is bringing down the curtain on its 30-plus-year military effort to pull the Islamic world into conformity with American interests and expectations. It’s about time. Back in 1980, when his promulgation of the Carter Doctrine launched that effort, Carter acted with only a vague understanding of what might follow.

In an Expert’s Brief I published yesterday, I reflected on Nelson Mandela’s achievements as the father of the democratic, non-racial South Africa that replaced the odious and repressive apartheid state. A lawyer himself–one of the first Blacks called to the South African bar–Mandela was devoted to the rule of law. Once in office, his governance was characterized by racial reconciliation, which he shrewdly promoted through the use of symbols. Like President Obama, he sought “teachable moments.”

On the fourth anniversary of his imprisonment in Cuba, former U.S. government contractor Alan Gross said he fears his country has “abandoned” him and appealed to President Obama to personally intervene in his case. In a letter to the president, sent via the U.S. diplomatic mission in Havana, Gross describes his isolation from the world, adding that his daughter and mother have been stricken by cancer, his wife has had to sell the family home in Maryland, and “my business and career have been destroyed.”
