What used to be a very secular Turkey is moved in the direction of becoming a more religious Turkey.

Russia's violated the Open Skies Treaty, refused to implement the Conventional Armed Forces in Europe Treaty.

These Russian and Chinese efforts are self-interested as these countries are doing very little to counter the myriad of terrorist threats across the region.

I am concerned about this role that Russia plays in northern Syria and how it impacts all of our relationships and especially the relationship between us and Turkey.

Syria is Russia's only remaining ally in the Arab world and it is clear to me that Putin and Russia are investing a great deal in Syria and the Assad regime's survival.

Ties between Russia and Turkey, a member of NATO, appear to be growing and solidifying.

Should we be concerned about Russia implementing its 'escalate to dominate' strategy in Syria and threatening the use of low-yield nuclear weapons to ensure the survival of the Assad regime?

The National Defense Strategy describes the greatest threat to U.S. prosperity and security as a reemergence of long-term strategic competition by revisionist powers.

Is it still our policy that Assad must go?

Is it too strong a statement to say that with Russia and Iran's help, Assad has won the civil war in Syria?

It's in our national security interest to make sure we don't do this twice.

Enough is enough when it comes to Assad. You're a war criminal, by any definition, and a big price.

The President said that Assad is an animal who killed innocent children by using chlorine gas.

Bottom line, I think you all make a heck of a team for the Army.

I think what we have done is ended the biggest nonproliferation program in the history of the world for no good reason, and I am going to try to fix that.

The Obama administration decided to abandoned construction of the MOX program. Do you consider that a withdrawal of that agreement?

I think we have to do two things at once: talk to the Russians about where we are headed but rebuild a nuclear deterrent force that is in decline.

I think it is okay to talk to the Russians about where we are going with nuclear weapons.
