Can the US and Cuba trust each other?

Barack Obama makes history with the first visit to Cuba by a US president in nearly nine decades.



A US presidential visit to Cuba was unthinkable 15 months ago.

It has been almost 90 years since the last visit by President Calvin Coolidge.

A US embargo has crippled the Cuban economy for more than fifty years.

But when President Barack Obama announced a thaw in their frozen relations at the end of 2014, he began a process of engagement he hopes will outlive his time in the White House.

Obama's historic visit to Havana is being seen as a way of cementing his diplomatic legacy.
