I think my best advice would be to separate Donald Trump, the president of the United States from whatever investigation is being conducted by the FBI. I mean, there is something to be said, frankly, about the need for the appointment of an independent prosecutor because the American people are entitled to have a full review of what happened as a result of what the Russians did during our election.

I think the primary message to the world is that the United States is going to remain the strongest military power in the world.

The fundamental premise is that neither the United States or the international community is going to allow Iran to develop a nuclear weapon.

The political and substantive reality is that the agenda has to change. I don't think they have any choice.

Clearly, Russia has lied to the world about what's going on in Ukraine. They have clearly violated the cease-fire agreements.

I think a quality that a national security adviser must have is the ability to set up procedures.

If you're a terrorist, you're a terrorist.
