Off their website, "The NSA/CSS core missions are to protect U.S. national security systems and to produce foreign signals intelligence information."
So yes. Foreign nationals are all fair game. One of their two explicit goals is to be able to listen to everyone and everything that does not fall under US privacy law.
Seems kinda hostile to treat all foreigners as "rights-free persons". The United States was built on immigration. I can't believe that the people in charge don't see how destructive this attitude is for the global neighborhood's relationship to the US.
It's surreal how quickly "we don't have an obligation to protect the rights of non-citizens" gets twisted into "we're allowed to abuse the rights of non-citizens".
You haven't really paid attention to the US's attitude towards the global neighborhood in the past century, have you? "Neighborly" isn't really the word I'd use to describe things like isolationism, walking softly and carrying a big stick, AMERICA WORLD POLICE, and the like. Even offshoring goes into this bucket, because cheap labor is cheap.
This is entirely besides the fact that we have roving unsanctioned militia units shooting people trying to illegally cross the US southern border, and we tried to build a goddamn fence to keep them out. An actual goddamn fence. And the immigrant-hostile legislation in Arizona and Alabama and Mississippi.
...yeah, in the 19th century, we were pretty psyched about immigration. We were still pretty happy about it in the 20th century, but we were building up muscle to throw down outside our borders. In the 21st century, WE ARE NUMBER ONE LA LA LA LA LA I CANT HEAR YOU OVER THE SOUND OF MY AWESOME.
You don't need to listen. Our governments listen to us then forward it to you. But its not as bad as you would think. John Key has heard that bad people are planning bad things at his briefings. It's very serious. This is for our protection. New Zealand.
So yes. Foreign nationals are all fair game. One of their two explicit goals is to be able to listen to everyone and everything that does not fall under US privacy law.
