We did not go to war in Afghanistan or in Iraq to, quote, 'impose democracy.' We went to war in both places because we saw those regimes as a threat to the United States.

I mean, we're going to probably debate the Iraq war for at least as long as I'm alive.

People change their habits. I know Americans who don't go to Paris because they think it is too dangerous.

The American people are pretty impressive in their ability to keep after something if they think it is doable.

I think all foreigners should stop interfering in the internal affairs of Iraq. Those who want to come and help are welcome. Those who come to interfere and destroy are not.

Donald Trump seems to be unconcerned about the Russian aggression in Ukraine. By doing this he tells them that they can go ahead and do what they are doing. That is dangerous.

To stay back from an intervention is not always a good solution.
