Renewed diplomatic ties between United States and Cuba may have a positive ripple effect on the rest of Latin America, says Inter-American Dialogue President Michael Shifter. The one issue that has unified all of Latin America against the U.S. has been its punitive policy towards Cuba, he said, and the restoration of diplomatic ties has been applauded by countries throughout the continent. This is Obama’s legacy, one that is very positive compared to that of other U.S. presidents, said Shifter. teleSUR
