The reality is that the United States military alone cannot be all things to all nations. We will sharpen the application of our resources, better deploy our forces in the world and share our burdens more and more effectively with our partners. And frankly, all our allies need to do the same.

My experience is that the director of the FBI is particularly important to just how aggressive an investigation will be into an issue. And once you remove James Comey, it creates a vacuum at the top. And the fundamental issue will be whether or not there is support at the highest levels within the FBI to continue to conduct that investigation. That's going to be the question mark.

I mean, the Taliban, my view is that they have been weakened.

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 know that young people sometimes, caught up in the moment, make some very foolish decisions.

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

I don't think I should penalize people who were doing their duty.
