Brazilian President Dilma Rousseff decided to condemn the US spying program on her country in a speech before the United Nations. The NSA spying program on Brazil, revealed in a story for Brazilian news outlet El Globo by Glenn Greenwald, already caused President Rouseff to cancel a trip to the US and has now led to a direct attack on President Obama before the international community at the UN.

Brazil’s president, Dilma Rousseff, has launched a blistering attack on US espionage at the UN general assembly, accusing the NSA of violating international law by its indiscriminate collection of personal information of Brazilian citizens and economic espionage targeted on the country’s strategic industries.

Rousseff’s angry speech was a direct challenge to President Barack Obama, who was waiting in the wings to deliver his own address to the UN general assembly, and represented the most serious diplomatic fallout to date from the revelations by former NSA contractor Edward Snowden.

Not only has the US spying program damaged relationships, it has caused such distrust that Rouseff and other leaders in Brazil are looking to break away from the US’ domination of the internet.

Washington’s efforts to smooth over Brazilian outrage over NSA espionage have so far been rebuffed by Rousseff, who has proposed that Brazil build its own internet infrastructure.

“Friendly governments and societies that seek to build a true strategic partnership, as in our case, cannot allow recurring illegal actions to take place as if they were normal. They are unacceptable,” she said.

Brazil has in recent years become an economic powerhouse rising to the seventh largest economy in the world. The consequences for the NSA spying program will negatively impact the political and commercial relations between the two countries. It also moves Brazil closer to China, a key US competitor in Brazil.

Apparently spying on the world is not without cost as US businesses looking to work in Brazil will soon find out. Perhaps it is time for those Americans with international and global interests to tell the US government to back off its arrogant posture of claiming the right to spy on the world’s communications. It seems such activity not only doesn’t promote US interests, it hurts them.
