Radicalism and extremism, while they are dangers, they exist in every society on some level.

The question that we, as a society, have to ask is, are our collective rights worth a small relative advantage in our ability to spy on other countries and foreign citizens? I have my opinion about that, but we all collectively have to come to our opinion about it.

As I said before, [patriotism] is distinct from acting to benefit the government - a distinction that's increasingly lost today.

In America, we collect more digital communications from America than we do from the Russians.

I would say the first key concept is that, in terms of technological and communication progress in human history, the Internet is basically the equivalent of electronic telepathy. We can now communicate all the time through our little magic smartphones with people who are anywhere, all the time, constantly learning what they're thinking, talking about, exchanging messages. And this is a new capability even within the context of the Internet.

When you use any kind of internet based capability, any kind of electronic capability, to cause damage to a private entity or a foreign nation or a foreign actor, these are potential acts of war.

All this is a blessing and a curse. It's a blessing because it helps people establish what they value; they understand the sort of ideas they identify with. The curse is that they aren't challenged in their views. The Internet becomes an echo chamber. Users don't see the counterarguments.
