When you decide to get involved in a military operation in a place like Syria, you've got to be prepared, as we learned from Iraq and Afghanistan, to become the government, and I'm not sure any country, either the United States or I don't hear of anyone else, who's willing to take on that responsibility.

Once the information is in the 40 to 70 range, go with your gut.

This is something else that is drilled into us in the military: Make sure you know who your replacement is, in case you become a casualty. So you have to have depth within an organization.

Perpetual optimism is a force multiplier. I am talking about a gung-ho attitude that says 'we can change things here, we can achieve awesome goals, we can be the best. 'Spare me the grim litany of the 'realist;' give me the unrealistic aspirations of the optimist any day.

The bottom line in all of it is that, in life, it's all about people.

Today I can declare my hope and declare it from the bottom of my heart that we will eventually see the time when that number of nuclear weapons is down to zero and the world is a much better place.
