European Union officials are demanding explanations from the United States, following revelations that the National Security Agency (NSA) spied on EU offices and targeted workers for surveillance.

And the calls for explanations may only grow, now that The Guardian has released more of NSA leaker Edward Snowden’s cache of American Intelligence documentation.  The Guardian reported the NSA had bugged or tapped 38 embassies and missions in Washington, D.C. The targeted offices included allies Mexico, Japan, and South Korea.

Earlier, the German newsmagazine Der Spiegel reported it got a look at a document showing the NSA eavesdropped on EU offices in Europe and Washington, DC.

“If these facts are confirmed, this will be totally inacceptable [sic],” said French Foreign Minister Laurent Fabius.

EU Parliament President Martin Schulz told Der Spiegel, “With all respect for the security interests of the United States, this should not develop into paranoia that friends are alienated.  I will ask the US ambassador for explanations.”

And inside America, many are questioning why the NSA even needs to engage in such wide-ranging spying, when its stated targets, al Qaeda and other such terrorists, have nothing to do with the offices named in the new reports.

“Spying has damaged US foreign policy, harming our reputation in a deep and long lasting way,” said Congressman Alan Grayson of Florida, adding that the revelations of wide-ranging spying and surveillance are “an I.Q. test for America.  Can’t we parse out what’s useful from what’s not useful?  Are we that stupid?”
