In Buenos Aires, Obama aims to boost Argentina's new leader

BUENOS AIRES — On a fence-mending mission, President Obama held up Argentina on Wednesday as an emerging world leader worthy of U.S. support, as he and Argentine President Mauricio Macri broke with years of recent tensions between their countries.

Yet Obama conceded that America’s history backing repressive regimes in the region had clouded its ability to take the moral high ground.

At Macri’s request, Obama has agreed to declassify U.S. intelligence and military records about the period known as the Dirty War, a gesture Macri said would help Argentinians “know what the truth is.”
