BEIJING, July 5 -- Wikileaks' latest revelation shows that Brazilian President Dilma Rousseff is another state leader that has been wiretapped by the U.S. National Security Agency (NSA), exposing again the U.S. hypocrisy and arrogance on cyber security.

According to a release by the whistleblower website, U.S. intelligence workers targeted Rousseff herself but also her aides, secretary, chief of staff and the presidential palace and even the phone in the Presidential jet.

Economy chiefs of the Brazilian establishment were under surveillance as well, with finance ministers and the governor of the Brazilian Central Bank on the target list.

The irony is that only months ago at the summit of the Americas in Panama, U.S. President Barack Obamareassured Rousseff that NSA would not spy on allied leaders anymore.

It seems Obama is either unable to call off the spying program on Rousseff as he has promised, or simply never meant to walk his talk.

Relations between the two countries have chilled for quite some time after former U.S. intelligence employee Edward Snowden revealed in 2013 that Rouseff was one of the foreign leaders whose phone was tapped by the NSA.

Though it is almost impossible for a third party to confirm the authenticity of Wikileak's claims regarding U.S. eavesdropping on Rousseff, many tend to believe they are true given the U.S. track record.

It has been revealed that the NSA monitored the phone conservations of at least 35 world leaders, including GermanyChancellor Agela Merkel, French President Francois Hollandeand several former French presidents.

Repeated wiretapping scandals have indicated that Washington has never treated anyone as a true friend, not even its allies: probably they are merely chess pieces for Uncle Tom to maintain its global supremacy.

Using the Internet and the most advanced technologies it has developed, Washington has gained access to a lot of private and classified information. Sadly, it has abused the advantage it has gained over other countries through its sophisticated spying and hacking programs.

Ironically, science and technology are a double-edged sword, which has also enabled Snowden and WikiLeaks to enlighten the world about the less than honorable things the United Stateshas been conducting in the dark.
