I have, as you know, the utmost respect for President Obama as a person.

If a huge number of people call for change, the government will have to react. If you want to avoid uprisings, or demonstrations, you need to respond to the peoples desperate need for change.

If we are addressing the issue of weapons of mass destruction, we need to send a uniform, consistent message that there is zero tolerance to any country who is developing weapons of mass destruction, North Korea included.

The Nobel Peace Prize is a powerful message. A durable peace is not a single achievement, but an environment, a process and a commitment.

Its up to any government to decide how to react to the denial of basic human rights anywhere in the world, including Egypt.

Whether weapons exist in Iraq, Saddam Hussein or post-Saddam Hussein, it is a serious enough issue that require that we continue to go and make sure that Iraq does not have weapons.

The simple fact is that there is a limited amount of water on the planet, and we cannot afford to be negligent in its use. We cannot keep treating it as if it will never run out.
