Reuters on the news the gasp NSA spied on several German ministers in addition to German Chancellor Angela Merkel:

Revelations by former NSA contractor Edward Snowden about wide-ranging U.S. spying have caused outrage in close ally Germany where privacy is an especially sensitive issue after the extensive surveillance by Communist East Germany’s Stasi secret police and by the Gestapo in the Nazi era.

The spying scandal was compounded by allegations that the German BND foreign intelligence agency helped the NSA and tracked other European targets on behalf of the NSA.
In the latest development, the German newspaper Sueddeutsche Zeitung and broadcasting network ARD reported, based on Wikileaks documents, that the NSA targeted 69 telephone numbers in the German government administration.

Among the officials being targeted were Economy Minister and Vice Chancellor Sigmar Gabriel as well as several of his deputy ministers, the reports said. British intelligence agencies were also involved in some of the operations, they said.

There is absolutely nothing surprising about here. The NSA is paid to spy on foreign government, and I believe any average, sane American citizen would applaud this type of activity.

The line was crossed once the NSA started spying in bulk on American citizens. However, like in spy movies, agents of any foreign government are completely understandable targets.
