We can deal with Russia on counterterrorism. We have and I think we are right now. That's easy.

Trump has got to define what he seeks to achieve with Russia, and then use diplomacy and sometimes coercion to achieve those ends. Right now, aside from this fight with ISIS, which I would underscore, you know, the Obama administration has been trying to fight ISIS with Russia for several years now.

Putin is now nationalist. And what he does is, he tells the Russian people, OK, you may have a little less chicken in your pot, but I'm making Russia great again. Look what we're doing all other the world. Everyone is paying attention to us. And Russia is a great power, on par with the United States and others.

We can deal with Russia on counterterrorism. We have and I think we are right now. That's easy.

I think something that's really understudied and misunderstood is the use of information.

Take cyber-capabilities. We have way more cyber-capability than Russia do. We could intervene in their elections easily. We choose not to do so because we're a different country. That's what Obama was trying to say.

It should never be the goal of U.S. foreign policy towards any country to have a - quote, unquote - "good relation." Then what? What do we get out of that? We get - Trump is helping the approval ratings amongst Russians. How does that advance American national security interests?
