US President Barack Obama’s landmark visit to Cuba is redefining what it means to be a good neighbour and a great power in today’s world. As the first American head of state to set foot in Cuba since 1928, that too 55 years after the US severed diplomatic relations with its spunky southern neighbour, Mr Obama is showing the way for an American foreign policy stripped of imperial hubris. His “new chapter” with Cuba and the rest of Latin America has upended centuries of Washington’s colonial arrogance and ideological oppression.
