An emboldened U.S. President Donald Trump has hinted that he has other countries in his sights after toppling Venezuela¡¯s Nicolas Maduro, leaving the world asking: Where¡¯s next?

Trump took aim at Colombia, Cuba, Greenland, Mexico and Iran in the space of a single half-hour exchange with reporters Sunday aboard Air Force One.

Trump, who openly campaigned for last year¡¯s Nobel peace prize and has scorned interventionism, now says he is enforcing Washington¡¯s right to do what it pleases in his backyard.
