Old Foes United in Their Grief: Presidents Carter and Castro Both Felt Close to our Late Prime Minister *** Each had their special relationship with Trudeau. While president in 1977-81, Carter sought advice on world affairs from the more senior statesman. "I think, more than any other person I know, Pierre Trudeau has been a symbol of unity, of human rights, of democracy and freedom around the world and was a great leader, even to help American presidents," Carter said. Castro's relationship with Trudeau was sealed during the PM's historic visit to Cuba in 1976. The trip opened a new era of friendship that continues today. The Cuban leader's affection is so strong that, before leaving Havana for the funeral, he declared a three-day period of mourning and had the flags of his nation lowered to half-staff.***
