For sure it's just what Mandela would have wanted, but does it amount to more than that?
The historic handshake between U.S. President Barack Obama and Cuba's Raul Castro at a memorial for Nelson Mandela on Tuesday was greeted on the streets of Cuba with surprise and hopes of improved relations.
Reaction was more muted in Miami, where Cuban exiles have had a hard time accepting Mandela's respect for Cuban leader Fidel Castro.
Castro's smile as Obama moved to shake his hand on the way to speak at the ceremony was seen by many Cubans as a signal of reconciliation, after more than a half-century of bitter ideological and political differences between the two countries whose shores are separated by only 90 miles.
"I never imagined such a thing could happen," said Yesniel Soto, a 25-year-old government worker.
"I see it as something that has begun to change, a change we are all hoping for," Soto said Tuesday morning on her way to work in Havana.
The two presidents' civil behavior towards one another was just the latest sign of a change of tone in the usually hostile rhetoric between the two governments.
Officials on both sides have spoken of a new gravity and pragmatism in their dealings with one another. And last month in Miami, Obama recognized for the first time Castro's efforts to reform the Soviet-Style economy, adding that U.S. policy, which includes long-standing economic sanctions, was outdated.
The handshake was not planned, and the two did no more than exchange greetings, a White House aide said.
"Perhaps the American and Cuban presidents grasp, with this handshake, that the work they have to do together is far easier than South Africa's struggle against apartheid," said Julia Sweig, director for Latin America Studies at the Council on Foreign Relations in New York.
"It can't hurt, but it's not significant," said Philip Peters, founder of the Cuba Research Center, and author of The Cuban Triangle blog.
"What matters is whether President Obama will conduct relations as he does with all other countries that have different political systems. That requires a decision, not a handshake," Peters added.
Cuban state-run television broadcast Tuesday's pressing of the flesh without commentary, simply as part of the footage of Castro's speech at the tribute in South Africa.
There has been no official comment on the encounter, but official blogger Yohandry Fontana played up the historic event, tweeting a photo of the handshake.
Cuban exiles down-played the greeting, the first between sitting presidents of the two countries since 2000.
"The handshake was unfortunate, but unavoidable and inconsequential," said Mauricio Claver-Clarone, director of Cuba Democracy Advocates in Washington, which promotes human rights.
"Much more important were Obama's words, which I believe were directed at Castro," he added, referring to the U.S. president's speech at the event.
"There are too many leaders who claim solidarity with Madiba's struggle for freedom, but do not tolerate dissent from their own people," Obama said, using Mandela's clan name.
Mandela was famously snubbed by Cuban exiles in Miami in 1990, when he visited the city after making comments in support of Fidel Castro.
Miami's Cuban-American mayor Xavier Suarez declined to honor Mandela with a proclamation or the keys to the city, prompting a 3-year boycott of Miami led by African-American business and community leaders.
During Mandela's 27 years or incarceration, Castro was a leading voice against apartheid when other world leaders were reluctant to speak out.
A letter signed by five Miami area mayors said Mandela's support for the Cuban leader, as well as Yasser Arafat and Muammar Gaddafi, was "beyond reasonable comprehension."
The only previous known handshake between U.S. and Cuban presidents since the 1959 revolution was in 2000 at the United Nations, when, in a chance encounter, Fidel Castro shook the hand of President Bill Clinton. That handshake, however, was not recorded for posterity as it took place out of sight of cameras.
While still U.S. vice president, Richard Nixon was photographed with Fidel Castro shortly after the Cuban Revolution in 1959, almost a full decade before becoming president. Jimmy Carter also met both Fidel and Raul Castro after leaving the White House.
In the context of Nelson Mandela as a peacemaker, Cuba's Catholic Church took note of the significance of the Obama-Castro handshake.
"One hopes that the example of Mandela continues being an inspiration to move further than a formal gesture like this, since Barack Obama and Raul Castro have said a number of times in their own ways that now is the time to change the style of the relations between Cuba and the United States," spokesman Orlando Marquez told Reuters.
