This is such a good idea, though too long in coming, as reported by Catholic Culture.

An excerpt.

Pope Francis played a key role in mediating talks between the US and Cuba, resulting in an exchange of prisoners and opening the way for the first direct talks between the neighboring countries in more than 50 years.

At a December 17 news conference in Washington, President Barack Obama acknowledged the importance of the papal intervention: “I want to thank Pope Francis, whose moral example shows us the importance of pursuing the world as it should be, rather than simply settling for the world as it is,” he said. Obama revealed that the Pope had written personal appeals to him and to Cuban President Raul Castro, urging a release of prisoners and a diplomatic thaw.

The Vatican later disclosed that in October, the Holy See had quietly arranged to receive diplomatic delegations from the US and Cuba for “a constructive dialogue on delicate matters.” The Vatican statement promised that the Holy See would continue to support diplomatic efforts to normalize relations between the two countries.

“The Holy Father wishes to express his warm congratulations for the historic decision taken by the Governments of the United States of America and Cuba to establish diplomatic relations, with the aim of overcoming, in the interest of the citizens of both countries, the difficulties which have marked their recent history,” the Vatican announced.
