Trump's Cuba 'next' threat

While officials from both countries have reportedly been in secret negotiations since February, the content of these discussions remains unclear.

The President's hostile rhetoric comes despite his recent decision to allow a sanctioned Russian oil tanker to break the blockade and dock in Cuba.

Some analysts believe this 'oil tanker diplomacy' could herald a Venezuela-style outcome, while others fear a return to total isolation.

The move is being closely watched by the international community as a potential sign of a broader regional strategy in the Caribbean.
