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.

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

Iran is isolating itself from the rest of the world.

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

The most important thing we can do is prosecute the offenders, deal with those that have broken the law and committed this crime. And if we can do that then we can begin to deal with this issue and send a signal this is not a problem that we are going to ignore in the United States military.

One of the principal qualities that you need as national security adviser is trust, the trust of the president. And that depends on truth and it depends on honesty.
