I will never cede the authority of our country or our security to any other nation. I'll never give a veto over American security to any other entity - not a nation, not a country, not an institution.

Remember the hours after September 11th when we came together as one to answer the attack against our homeland. We drew strength when our firefighters ran upstairs and risked their lives so that others might live; when rescuers rushed into smoke and fire at the Pentagon; when the men and women of Flight 93 sacrificed themselves to save our nation's Capitol; when flags were hanging from front porches all across America, and strangers became friends. It was the worst day we have ever seen, but it brought out the best in all of us.

I voted to threaten the use of force to make Saddam Hussein comply with the resolutions of the United Nations.

As I have said for two years now, when Osama Bin Laden and al-Qaeda were cornered in the mountains of Tora Bora, it was wrong to outsource the job of capturing them to Afghan warlords who a week earlier were fighting against us.

There is no bigger judgment for a president of the United States than how you take a nation to war.

I know something about aircraft carriers for real.

I accept that friends of ours have decided that the President's non-strike has somehow impacted perceptions of us. But I believe they are dead wrong and I think the critics are dead wrong, and here's why. The President [Barack Obama] made his decision to strike. He announced his decision to strike publicly. And the purpose of the strike was to get the chemical weapons out of Syria. That's the purpose.
