For years, especially after World War 2, the US has interfered in the electoral process in many developing countries to tilt the election to a candidate who support their own interests. The Russians have done the same. But it is unusual for both countries to interfere in the election of their archenemy.
It is US and British intervention in Guyana that has led to the underdevelopment and the racial divisions in the country today. Imagine the outrage in Guyana then. The US also need to do some soul searching and reflect upon how much pain and suffering it has caused people around the world...all in the name of fighting communism.
