The language of North Korea is always bombastic. But what has really changed is the acceleration of their nuclear program, the likelihood that they have more and more weapons, and the acceleration of the testing of ballistic missiles in very, very aggressive ways towards Japan.

We can't be French and Muslim at the same time. And that's exactly what ISIS wants that population to think.

I think we have started accelerating over the past years. It's a modernization of NATO. It's at air, it's at sea, it's undersea, it's in cyber. Estonia in 2007, hit by Russian cyber-attacks. So what you see there with those exercises are critical.
