Yet while on my trip to the Middle East, the London bombings occurred. This was yet another stark reminder that if we don't fight terrorists abroad, they just get closer to our home.
The terrorists' only rules? That there are no rules, and this gives them a major advantage.
President Obama and Hillary Clinton most definitely signaled to Islamic State leaders that they had no intention of seriously challenging them, or even of calling radical Islamic terrorism by its name.
The majority of the world's Muslims do not believe that terrorism is a legitimate strategy or that Islam is incompatible with democracy.
The return to normality is a defeat for the terrorists.
ISIL's widespread reach through the Internet and social media is most concerning, as the group has proven dangerously competent at employing such tools for its nefarious strategy. ISIL uses high-quality, traditional media platforms as well as widespread social media campaigns to propagate its extremist ideology.
I don't believe we are, because I believe that just as 9/11 was an attack on a very populous area, terrorism also looks to see where you can go and where you're not expected.
Radical Islamic jihadists have a long-term vision. And if they have to stay in Europe to obtain a citizenship, to ultimately travel to the United States, and if it takes them five years or ten years, they're okay with that. History has proven that.
A terrorist network that believes a nation so tested will fold under pressure of a few horrific acts may capture its attention, but will not achieve its submission.
I think we need to go after Baghdadi, as well, make that one of our organizing principles. Because we've got to defeat ISIS, and we've got to do everything we can to disrupt their propaganda efforts online.
I am convinced that international terrorism gave itself the goal of not allowing the re-election of Bush. The statement by bin Laden in the final stages of the pre-election campaign is the best confirmation of this.
Al Qaeda will always focus on us, the United States. And they will take advantage of any situation.
The West only talks about how you can militarily defeat the terrorists, but terrorists are very difficult to defeat because they can appear anywhere.
Terrorism is to be used toward an end. It is not an end in itself.
Collins and his followers used terror tactics—the first major use in the 20th century.
ISIS takes a long-term approach to its apocalyptic war with West - we have to do the same.
Notwithstanding the repeated denials of governments – terrorism can, in the right conditions and with the appropriate strategy and tactics, succeed in attaining at least some of its practitioners’ fundamental aims.
Instead, the terrorists see just what they were hoping for, our unity gone, our resolve shaken, our leaders distracted. In short, they see weakness and opportunity.
There is a worry about a bomb being implanted in a human being and placed on an airplane. So, I think there is a lot to worry about.
I still wonder if the United States realizes how much planning went into this. When we talk about "mindless terrorists," we are lying to ourselves.
Did either the nonexistent or the measured response after a series of attacks on Americans the past decade - in Lebanon, Africa, Saudi Arabia, New York, and Yemen - suggest to our terrorist enemies that it was wrong and unwise to kill reasonable and affable people, or did the easy killing imply that self-absorbed and pampered Lotus-eaters would not much care who or how many were butchered as long as it was within reasonable numbers and spread out over time?
