Congress hasn't declared war on the countries - the majority of them are our allies - but without asking for public permission, NSA is running network operations against them that affect millions of innocent people. And for what? So we can have secret access to a computer in a country we're not even fighting?

There are cyber threats out there, this is a dangerous world, and we have to be safe, we have to be secure no matter the cost.

These [NSA] programs were never about terrorism: they're about economic spying, social control, and diplomatic manipulation. They're about power.

We have to be able to ask questions in order to answer them.

We decentralise permissions over the use of our communications.

When the United States cannibalize dollars from the defensive business of the NSA, securing our communications, protecting our systems, patching zero-day vulnerabilities, and instead we're giving those dollars to be used for creating new vulnerabilities in our systems so that they can surveil us and other people abroad who use the same systems.

The great fear that I have regarding the outcome for America of these disclosures is that nothing will change. [People] won't be willing to take the risks necessary to stand up and fight to change things And in the months ahead, the years ahead, it's only going to get worse. [The NSA will] say that because of the crisis, the dangers that we face in the world, some new and unpredicted threat, we need more authority, we need more power, and there will be nothing the people can do at that point to oppose it. And it will be turnkey tyranny.
