I’m surprised at how fainthearted we sometimes are, and how quickly we lose courage.

If you weren't embarrassed from yesterday, then don't come into this gym. You're not needed or wanted here. We need the mindset to shift, because that was embarrassing.

I don’t want my son serving alongside troops who are out of shape, or in combat units with females who can’t meet the same combat arms physical standards as men.

As the Democratic Party, we have a lot of work to do to make up for our failures in the past. We got crushed in this last election.

No matter what the aggressor intends to do, when the world is truly united, it is then the world, not the aggressor, determines how events develop.

So the 20th century taught the world not to use nuclear weapons and not to proliferate. This is not a good strategy because recent history has shown that wars could erupt with equal devastation.

In the past, human progress had to come at the cost of the environment. If we wanted energy, we had to burn wood or we had to burn fossil fuels. If we wanted to grow more food, we had to expand farmland, often at the cost of forests. But technology and innovation means we're very quickly decoupling these impacts, such that this conflict is no longer true.

[Angela Merkel] showed what can be achieved when politicians take the right course of action and work to find solutions to the world’s challenges rather than simply shift responsibility to others.
