WENDY SHERMAN, Former State Department Official:

Well, first of all, all of the things that Walid just outlined were not discussed in Mr. Trump's speech at all yesterday.

In fact, the strategy that Mr. Trump put on the table, other than the extreme vetting, is exactly what President Obama and Secretary Clinton have worked toward. That is an international coalition with local troops on the ground, having a very aggressive strategy in the cyberworld to stop the financial flows.

All of these are part of a multivector strategy that has been under way under President Obama for quite some time now and is actually having success.

Just today, Secretary of Defense Carter said that Syrian democracy forces had indeed taken back Manbij, which is a very key transit point, and now opens the way to ultimately getting to Raqqa, which ISIL has said is its centerpiece for a caliphate, which is disappearing on the ground in Syria.

There is a very complex environment in the Middle East. In that, Walid is correct. But it can't come without some knowledge and some background. And every day, we get a different message from Mr. Trump. I would like to know, does he still support torture, which is not the American way and doesn't bring results?

Does he still believe that we ought to be killing innocent civilians if there is a family of terrorists that have nothing to do with the terror? Is he someone who still believes in, as you pointed out, Hari, sending thousands and thousands of troops? Mr. Trump has been on all sides of that issue over the history of the last several years.

So it's very difficult to know whether Mr. Trump stands and whether he has an understanding of the complexity of the situation and the progress that's being made, but the progress that is still absolutely needed to protect our homeland and to make sure that Americans feel safe and secure.
