Even if we give first priority to the destruction of terrorist networks, and even if we succeed, there are still governments that could bring us great harm. And there is a clear case that one of these governments in particular represents a virulent threat in a class by itself: Iraq. As far as I am concerned, a final reckoning with that government should be on the table.

I had a detailed plan for my life, but it turned out life had a completely different plan for me. And I feel joy that I have work that feels like it justifies pouring everything I have into it. I never have fallen prey to the illusion that there's any job with as much ability to influence the future as that of President of the United States, but I do feel grateful that I found other ways to do work that serves the public interest.

Those who are quick to feel disrespected often have a spiritual vacuum in their lives, because they feel disconnected to the love of their Father in Heaven.

Where solar energy is concerned - and wind energy and battery storage and electric vehicles and efficiency technologies - that is what we are now seeing. So, yes, I'm very optimistic, but anyone who works on the climate crisis has an internal struggle between hope and despair. I won't deny that, but hope has always prevailed in my outlook.

The climate, financial and national security crises are all connected. They share the same cause: Our [the USA's] absurd dependency on foreign oil. As long as we need to spend billions of dollars each year to buy foreign oil from state-run oil companies in the Persian Gulf, our problems of a trade deficit, a budget deficit and a climate crisis will persist.

The sooner we switch away from carbon-based fuel and start relying on renewable energy sources available in the United States, the sooner we will grow our economy by creating the millions of new jobs that will come from retrofitting homes and businesses, building smart grids, renewable energy systems and planting trees and all the rest. We need to create a lot of jobs that can't be outsourced.

I remain optimistic that ultimately free speech and a free press where individuals have access to the dialogue will have a self-correcting quality.
