There are times where I've made mistakes or our administration hasn't always aligned ourselves with the values we need to align ourselves with. It's a work of constant improvement.

The United States, therefore, works to ensure that any actions we take are consistent with international laws and norms - including those reflected in the Law of the Sea Convention. It's worth remembering that our presence in the region is nothing new.

You got into these small towns in Pennsylvania and, like a lot of small towns in the Midwest, the jobs have been gone now for 25 years and nothing's replaced them. And they fell through the Clinton Administration, and the Bush Administration, and each successive administration has said that somehow these communities are gonna regenerate and they have not. And it's not surprising then they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations.

Oftentimes, misunderstandings and antagonism surfaces most strongly when economic times are tough. And that's not surprising. If everybody is working and feeling good and making money and buying a new house and a big screen TV, you're less worried about what other folks are doing.

Of course, there is no question that Libya - and the world - will be better off with Gaddafi out of power.

But broadening our military mission to include regime change would be a mistake.

Rand`s [Paul] a libertarian. He has a view of the world that I don`t share. He said that we shouldn`t have any troops in Iraq. He agreed with Obama that was a disaster. When there was a chance to do something constructive about Syria with a no-fly zone, he said we don`t need one.

Constitution is a living document; no strict constructionism.
