The latest Snowden leak lists the countries where the NSA is allowed to spy, which is to say pretty much everywhere:
Presumably, the NSA preemptively asked for (and got) authority in most of these countries before it had a specific reason. Although, it’s certainly possible that at some point the NSA decided it really needed explicit permission to spy in San Marino, Saint Lucia, the Grenadies, Samoa, Palau, and other island nations that do not present an immediately obvious intelligence draw.
The second thing you’ll notice is the only four nations not included on the list: the United Kingdom, Canada, Australia, and New Zealand. (There is also a fifth, South Sudan, although it was not yet independent as of 2010 and I’d bet everything I own that they’re now on the list.) Those four countries, all fellow Anglophone nations of significant English descent and former members of the British Empire, are members with the United States in an agreement known as 5-Eyes. … But the vast, vast majority of the world is not part of 5-Eyes, and that means that they’re subject to NSA spying on their government, whether they like it or not.
Waldman considers how the rest of the world must be reacting to this news:
I suspect that when most Americans hear that we’re spying on people’s phone and e-mail conversations in almost every country in the world, they think, well, that’s just what we have to do — we’re the United States. As citizens of the global hegemon, we take certain things for granted, like the fact that our soldiers will be stationed in dozens of countries around the globe, or that everyone everywhere should speak English. …
But we should be aware that if you live in another country and you hear that the United States might be reading your e-mails — or that, in what seems to be a test run for later application in other places, the NSA is recording the audio of literally every cellphone conversation in the Bahamas — you’re going to be uncomfortable, to say the least, about the reach of U.S. power. I’m not talking about violent, flag-burning anti-Americanism, but about a far more common feeling, widespread even among people who like American music and movies and share many of our values. It’s the feeling that the United States treats the rest of the world like its subjects, people whose liberties and sometimes even lives can be swept aside whenever we find it in our interest.
