WASHINGTON — For President Barack Obama, an embarrassing diplomatic rebuke by Brazil has compounded an already troublesome stretch for the White House both at home and abroad. Brazilian President Dilma Rousseff announced Tuesday that she was putting off a state visit to the US next month to protest an American spy program that has aggressively targeted her nation's government and private citizens alike. Rousseff's decision deepened the global fallout for Obama from revelations about National Security Agency surveillance programs, which have also angered many Americans. The announcement also came amid criticism of Obama's public shifting over the threat of US military action against Syria. Some foreign policy analysts say such issues raise questions about Obama's standing around the world. “The real issue becomes, how does this affect American influence in the world?” said Carl Meacham, director of the Americas program at the Center for Strategic and International Studies. He called Rousseff's action “almost unheard of.” Rousseff said she wasn't outright canceling her trip but was postponing it. The White House portrayed the postponement as a joint decision reached between the two presidents. “They both look forward to that visit, which will celebrate our broad relationship,” White House spokesman Jay Carney said. “We're certainly acknowledging the concerns that these disclosures have generated in Brazil and other countries.” Throughout his summer travels abroad, Obama has been followed by criticism of the government's spying programs. While the anger has been particularly intense in privacy-protective Europe, Rousseff was also incensed about revelations that the US intercepted her communications with aides. Classified documents leaked by former NSA systems analyst Edward Snowden also showed that the NSA hacked the computer network of Brazil's state-run oil company Petrobras and that the agency scooped up data on billions of emails and telephone calls flowing through Brazil, an important hub for trans-Atlantic fiber optic cables. The revelations added to longstanding suspicions in Brazil about the American government. Domestic political concerns clearly factored into Rousseff's decision to postpone her trip to the US She's facing a re-election fight next year that became more competitive after nationwide anti-government protests in June. Tim Ridout, a fellow at the Washington-based German Marshall Fund, said the Brazilian leader was also seeking to show strength on the world stage. “I see this partly as a way for Brazil to exert its influence and say, ‘We can stand up to the United States and serve as a counterbalance,'” Ridout said. Rousseff's visit to the US was announced back in May, just weeks before the NSA programs were made public. The White House, which has been seeking to deepen ties with the economically booming Brazil, planned to honor her with a state visit full of pomp. She would have been the first Brazilian leader to be honored with a state visit to the US since 1995. — AP
