Diminish us across the board. They [Russians] do not wish us well.

Realism is important in foreign policy. You have to be realistic about what you can achieve, and about the pitfalls, and problems along the way, of which there are plenty. Nothing is easy. It's always rough.

The Russians are using the tools at their disposal to weaken Western solidarity, to create doubt, to support nationalist parties, just as the old Soviets supported leftist parties. We need a united Western response to this multi-pronged threat.

John Kerry tried to work with the Russians on Syria, and the man was honorable, because he was trying to do the right thing, and frankly, playing a very weak hand, a hand that was weak not because of him, okay. He did the best he could, but I will say this to his enormous credit: he never offered a dirty deal. You can have Ukraine if you only help us out on Syria. Never - he never did that.

It was my honor to have done what I could do to help. I learned to never underestimate the possibility of change, that values have power and that time and patience can pay off, especially if you`re serious about your objectives.

Russia is an aggressive revisionist power. And they are working - there's evidence they're working to interfere not just in our electoral process, but the electoral processes of Europeans with the same toolkit - money, fake news, propaganda, and what those Soviets used to call aktivniye meropriyatiya, active measures. This is serious.

Internal reform in Russia would require a better relationship with the West.
