My most solemn duty is to protect this nation and its people against further attacks and emerging threats.

Al-Qaida terrorists and their affiliates are at war with the United States, and those that we capture - like other prisoners of war - must be prevented from attacking us again.

Officials have not said if there are any groups suspected to be behind the attack.

For example, why would foreign terrorists want to attack you and other Americans?

They would have captured them within hours, because for many hours after the attack on my house they were still in the hills around my house.
