I take offense at the comparison to the run-up to the Iraq War.

Mr. Putin clearly wants to get Ukraine within the Russian sphere of influence. He does not want Ukraine to affiliate with the European Union. Obviously, he doesn't want it to affiliate with NATO.

He doesn't want Ukraine to be a thriving democracy that would set an example that some people in Russia might notice and say, why there, not here?

The last time Russia did that on a significant scale, it ended up bringing about regime change inside then the Soviet Union.

The grim aftermath of America`s strategic and moral failure will reinforce questions about U.S. reliability among friends and foes far and wide.

Whatever it is we do in this part of the world, multilateralism will prove essential. We simply cannot deal adequately with China's power and China's reach unilaterally.

the idea that Secretary Pompeo can speak at the RNC Convention, in his personal capacity betrays a basic misunderstanding any individual gives up his/her personal capacity to speak on foreign policy when he she takes the job. It is public…

The E.U. is an instrument on the trade issue. It is our largest trading partner and investor.

This is not foreign policy. These are acts of aggression against individuals.

We ought to have a race to the top, not a race to the bottom.

the EU is a friend not a foe. European countries offer the best set of partners available to the United States for tackling global challenges.
