as Washington ramps up pressure on the communist island fresh after removing Venezuela's president. Rubio, a Cuban-American who has spent his political career hoping to topple Havana's government, is also looking for sustained cooperation on Venezuela and troubled Haiti as he takes part in the summit of the Caribbean Community, or CARICOM, which does not include Cuba. After attending President Donald Trump's State of the Union address to Congress, Rubio flew overnight to join the summit in Saint Kitts and Nevis, a sun-kissed former British colony of fewer than 50,000 people. Rubio became the highest-ranking US official ever to visit the tiny country, the birthplace of one of the United States' founding fathers, Alexander Hamilton. Trump has reoriented foreign policy toward the Western Hemisphere through his "Donroe Doctrine" in which he has vowed unrepentant intervention to advance US interests. After US forces snatched Venezuela's leftist leader Nicolas Maduro in a January 3 raid, the Latin American country has been forced to cut off its crucial oil shipments to Cuba. This has plunged Cuba into a further economic morass with fuel shortages and rolling blackouts. Speaking at the opening of the CARICOM summit on Tuesday, Jamaican Prime Minister Andrew Holness warned that a further deterioration in Cuba will impact stability across the Caribbean and trigger migration -- the top political concern for Trump. "Humanitarian suffering serves no one," Holness said. "A prolonged crisis in Cuba will not remain confined to Cuba." (Bssnews)
