It is a very real concern and my view is that everything changed on September 11th and the procedure, the policies that were in place prior to September 11th no longer should apply.
There is no more dangerous country in the world today than Pakistan.
A.I. poses a potential threat more dangerous than nuclear weapons.
I think a lot of programs, policies have been put in place since 9/11, have prevented a 9/11-style attack. On the other hand, I think the threat has become greater, not lesser.
Snowden has enough [sic] information to cause harm to the U.S. government in a single minute than any other person has ever had. The U.S. government should be on its knees every day begging that nothing happen to Snowden, because if something does happen to him, all the information will be revealed and it could be its worst nightmare.
In a nuclear age, each of us is threatened when peace is not secured everywhere.
In a world which is armed to its teeth with nuclear weapons, every quarrel or difference of opinion may lead to violence of a kind quite different from what is possible today.
I've been under security protection since 1978.
My own death threats have declined considerably.
Today, the danger of some sort of a nuclear catastrophe is greater than it was during the Cold War, and most people are blissfully unaware of this danger.
In the future, the cyber threat will equal or even eclipse the terrorist threat.
When you wear a wire, you're always in danger.
The truth is, as long as nuclear weapons exist, we are not safe.
There Is No Terrorist Threat In This Country. This Is A Lie. This Is The Biggest Lie We've Been Told.
Climate change remains the biggest threat to our civilisation, economy and security - even bigger than Brexit.
Russia is the biggest menace in the world led by the most menacing guy in the world.
The threats against me are not only in Holland, but outside the country as well. We are talking about very serious threats on the part of different terror groups, and when you are aware of the extent of the threats, it's only human to think that something will indeed happen.
There is no such thing as perfect security, only varying levels of insecurity.
Look, we constantly live looking at the issue of the threat of terrorism.
Hillary Clinton is a threat to the rule of law and to our safety and security.
Clearly, climate change is an extremely important threat to us.
The greatest threat now is a 9/11 occurring with a group of terrorists armed not with airline tickets and box cutters, but with a nuclear weapon in the middle of one of our own cities...there's a high probability of such an attempt.
The evil within the fantasy genre tends to be threatening to the heroes within the story, but not to the reader - or not to the viewer, in the case of cinema - and that's why I think it's more palatable and something that is more easily embraced for a lot of people.
I'm worried that too many people, both in politics and out, don't appreciate the seriousness of the threat to American security and the evil of the enemy that faces us -more evil or as evil as Nazism and probably more dangerous than the Soviet communists we fought during the long Cold War.
It does not matter what position you take on the Left, you are safe and secure. But that is not at all the case for positions that the Right take on. You are not safe and secure, so you travel with bodyguards
