Last weekend, the Obama administration eased travel restrictions to Cuba. And now the Cuban government has decided to thank them by suspending postal service to the U.S. indefinitely:

The suspension follows the introduction of stricter security measures by the US last year after the attempted mailing of explosives from Yemen.

The Cuban postal service says large amounts of mail were refused entry and returned in the following months.

Correspondents say the cost of so many returns may have led to the decision to stop the service.

It was President Obama who resumed postal service between the U.S. and Cuba (via third-party countries) back in 2009. Before that, it had been blocked for 42 years.

Establishing better relations with Cuba was one of Obama’s campaign promises, and so far it’s turned out to be a total failure. Despite the administration’s attempts to ease the embargo on Cuba, Havana has responded with indifference — and now this. Obama’s election was supposed to herald a new age of diplomacy between the U.S. and South America. Instead, his overtures toward both Cuba and Venezuela have blown up in his face.
