The US National Security Agency has been accused of spying on Brazil's biggest oil company, Petrobras, following the release of more files from US whistleblower Edward Snowden.
The latest disclosures, which aired on Brazil's Fantástico news program, have led to accusations that the NSA is conducting intelligence-gathering operations that go beyond its core mission of national security – often cited as the key distinction between the agency and its counterparts in China and Russia.
The revelations are likely to further strain ties between the US and Brazil ahead of a planned state dinner for president Dilma Rousseff at the White House in October. Bileteral relations have already been muddled by the earlier release of NSA files showing the US agency intercepted Brazilian communications and spied on Rousseff and her aides.
I guess its just more evidence that to the US, "national security" means the interests of Big Oil.
