An all-volunteer army is best suited to fight the new wars of the 21st century.
I'm not surprised that people are unsettled because of war. The enemy has got a powerful tool, and that is to get on your TV screen by killing innocent people. And my job is to continue to remind the people it's worth it, we're not going to retreat hastily, and we're not going to pull out of there before the job is done. And we have got a plan for victory.
