National Security

The [Barcelona] attacks, to me, show both the strengths and weaknesses. The strengths are obviously that [the Islamic State] has an array of supporters, especially in Europe, that it can call upon to do attacks. The weakness, though, is that it has had difficulty doing more sophisticated operations.

The dual-freeze approach is China's attempt at buck-passing and moral equivalency between U.S. actions and North Korean actions. ... Buck-passing in the sense that Beijing is not making a genuine effort to leverage a freeze. They are making a genuine effort to pin responsibility on the United States.

[U.S. military capabilities in the Pacific are] very imposing, very impressive [and are intended] to deter the North from any kind of potential actions. But if the North were to act, the U.S...would have to deploy far more to the peninsula and the region as quickly as possible.

[So far there have been no efforts to evacuate U.S. citizens living in South Korea.] That would be the clearest indication that we were headed toward war. And I don't think we are.
