Today, few terrorist organizations still employ the 'al-Qaeda model' in which individuals travel to terrorist training camps overseas and then are deployed to the West to inflict atrocities.

Right now, American law bars the admission of aliens suspected of terrorist activity - but not of terrorist sympathies.

If the terrorists have the sympathy of people, it's much harder to find them. So we need people on our side, and that leads us to be responsible leaders of the world, show some concern with the problems.

When terrorists attacked the symbols of our national unity and strength, they failed to realize that they were just symbols of our strength. The real strength of our nation comes from our people - not our buildings.

When it comes to tyrants, dictators and terrorists, strength and the threat of force is the only language they understand.

There are many who lust for the simple answers of doctrine or decree. They are on the left and right. They are not confined to a single part of the society. They are terrorists of the mind.

The sad fact is that the same terrorist scenarios, if they occurred in five different States, there could be five different sets of responses to the American people. We need, at a minimum, a level of coordination on communicating threats to the public.

In a sad twist of fate, the bill to reauthorize the Patriot Act was debated on the floor of the House of Representatives the same day that terrorists struck again.

I'm proud of my invention, but I'm sad that it is used by terrorists.

We will be safer from terrorist attack only when we have earned the respect of all other nations instead of their fear, respect for our values and not merely our weapons.

We know that no algorithm can solve global poverty; no pill can cure a chronic illness; no box of chocolates can mend a broken relationship; no educational DVD can transform a child into a baby Einstein; no drone strike can end a terrorist conflict. Sadly, there is no such thing as 'One Tip to a Flat Stomach.'

Every time I tell my story, I feel that I am taking some power away from the terrorists.

Markets rebounded quickly from morning jitters after the London Thursday terrorist bombing.

Every lethal terrorist attack in the United States since 9/11 has been carried out by an American citizen or a legal permanent resident, not by recent immigrants or by refugees. So tamping down immigration won't fix the real issue, which is 'homegrown' terrorism.

However, we do not lack anti-terrorist laws. I do not believe that the recent London bombs were the result of any deficiencies in our legal system.

In my book, I detail the critical information we obtained from al Qaeda terrorists after they became compliant following a short period of enhanced interrogation. I have no doubt that that interrogation was legal, necessary and saved lives.

I have strongly rejected the proposal to pardon and transfer her to the United States. I do not have the legal power to pardon terrorists and even if I did, I would not use it.

Once the attacks occur, as we learned on Sept. 11, it is too late. It makes little sense to deprive ourselves of an important, and legal, means to detect and prevent terrorist attacks while we are still in the middle of a fight to the death with al Qaeda.

The military tribunals currently underway at Guantanamo Bay create a clear legal process, as affirmed by the U.S. Supreme Court in Hamdi v. Rumsfeld, for adjudicating the cases of these terrorists, when possible. Those efforts would be severely undercut by moving the detainees to the United States.

President Bush has shown great leadership. He has said that the 21st century will not be ruled or dictated by terrorists, dictators, and murderers. He is absolutely right. God bless him for his resolve.

The whole macho thing has to be reexamined. Because in my view, the Bush administration was weak, not strong. To engage in a policy of torture is a weak policy. Because ultimately, it encourages the terrorists. It undermines our own values. It corrupts our system. And it doesn't get good intelligence.

The wrongful arrest of tens of thousands of British Muslims after the September 11 attacks can be explained by the very poor intelligence the police had, and, just possibly, excused by the fact that a terrorist action in Britain linked to British Muslims would have been hugely damaging.

We worked to develop our own operations to advance U.S. counterterrorism objectives by penetrating terrorist safe havens and collecting intelligence that would inform policy and enable our own operations.

We can't gather the intelligence we need to foil future attacks, if we are blindly granting terrorists the right to remain silent. But for some reason, we've already done that - with the terrorist who tried to bring down Flight 253.
