Rousseff summed it all up rather succinctly in a blunt speech at the United Nations last September, denouncing "a situation of grave violation of human rights and of civil liberties; of invasion and capture of confidential information concerning corporate activities, and especially of disrespect to national sovereignty."
But now, thanks to additional leaked documents described by Ryan Devereaux, Glenn Greenwald, and Laura Poitras in The Intercept, we find there is another U.S. agency working with the NSA that poses similar threats: the U.S. Drug Enforcement Agency (DEA). According to the documents, there is a "two-way information sharing relationship" between the DEA and NSA: it's not just the NSA helping the DEA catch drug traffickers, but also the DEA helping NSA with its non-drug-related spying programs.
From the Intercept: "DEA is actually one of the biggest spy operations there is," says Finn Selander, a former DEA special agent ""Our mandate is not just drugs. We collect intelligence."
This is potentially an even bigger breach of diplomatic trust than the NSA spying that Rousseff denounced at the U.N. Governments allow the DEA access to military, police and intelligence resources -- sometimes including phone-tapping -- as part of a collaborative effort with the United States to fight organized crime. They do not expect that by doing so they are unwittingly assisting the NSA and the enormous U.S. intelligence apparatus with unauthorized spying for political or commercial purposes.
Meanwhile in Brazil, although both Rousseff and former President da Silva have called for apologies from President Obama for the abuses, U.S. officials have made it clear that this will not happen (in the words of former U.S. Ambassador to Brazil Thomas Shannon, "you should not expect an unexpected gesture"). Nor has Washington given reasonable assurances that such abuses won't occur in the future.
