Kay Hagan: “I think that tactical nuclear weapons are an integral part of a strategic security.”

I think that's very important, because it certainly would degrade their capability.

While a strong moderate military force is essential, I do believe success on the battlefield can only set the condition for the political solution in Syria.

Do you see the presence of radicalized Westerners fighting with ISIS and the Khorasan as a threat to the United States?

The United States cannot bear this fight alone, and a strong coalition, including the neighboring Arab states, is obviously critical to destroying ISIS.
