Think of ISIS as a pathogen that preys on weak hosts in the Muslim world. In fact, there is something of a political law: The weaker a Muslim state, the stronger will be the presence of ISIS or like-minded groups.
— Peter Bergen
President Obama and a small team of senior national security officials were in the unusual position of acting as al-Awlaki's jury, judges, and de facto executioners.
What made al-Awlaki so influential is that, unlike a number of leaders of al Qaeda such as Osama bin Laden, he was a cleric, so he could present himself as a leading religious figure. Second, because al-Awlaki had spent much of his adult life in the States, he communicated with his followers in colloquial, accessible American English.
Trump's pronounced anti-immigrant stance is reminiscent of both Le Pen in France and Orban in Hungary, although he is far from alone in taking such positions in much of today's Republican Party.
Bush administration officials, of course, deny that they didn't take the threat urgently enough, but there is no debating that in their public utterances, private meetings, and actions, the al Qaeda threat barely registered.
The diagnosis that poverty, lack of education, or lack of opportunities have much to do with terrorism requires a fundamentally optimistic view of human nature. This diagnosis leads to the prognosis that all we need to do to solve the terrorism problem is to create societies that are less poor, better educated and have more opportunities.
I was the only outsider to visit the Abbottabad compound where bin Laden lived before the Pakistani military demolished it.
Islam is, to be sure, a big tent, and the one and a half billion Muslims in the world run the gamut from mystical, moderate, pacific Sufis to Salafists.
Virulent anti-Semitism is, of course, a staple of militant Islamist ideology.
Trump has claimed he knows more about ISIS than America's leading generals. Clearly, this is also total nonsense; he doesn't seem to have done the slightest thing to educate himself about ISIS.
The dangers of TATP bombs can be seen in the case of Matthew Rugo and Curtis Jetton, 21-year-old roommates in Texas City, Texas. They didn't have any bomb-making training and were manufacturing explosives in 2006 from concentrated bleach when their concoction blew up, killing Rugo and injuring Jetton.
I stepped into the bedroom where he was killed and looked up at the ceiling, where you could still see the patterns of blood that had spurted from bin Laden's head when the bullet fired by a U.S. Navy SEAL tore through the terrorist leader's face.
At one point people in al Qaeda were actually drawing monthly paychecks when they were based in Sudan.
The image we have of bin Laden in his final years in Abbottabad is of an aging man with a graying beard watching old footage of himself; just another suburban dad flipping though the channels with his remote.
I've interviewed multiple people who know bin Laden... who tend to have a universal picture of what he's like, which is: modest, retiring, unassuming, kind of thoughtful - lots of things that don't fit with a mass murderer, which he is as well.
The civil war across the Middle East between the Shia and the Sunni empowers groups like ISIS and al Qaeda who claim to be the defenders of Sunni rights against Shia attack.
Six years after al-Awlaki was born, his family moved back to Yemen, but he returned to the States for college and remained there for much of his adult life.
If the party of Lincoln wishes to become the party of intolerance, selecting Trump to be its presidential candidate is a good way forward.
There is no hint that Trump wishes to engage in or to foment violence against the enemies, such as immigrants, he has identified as undermining the American way of life.
Trump, of course, has been very wrong in the past about important issues such as President Barack Obama's place of birth and Mexican immigrants, but the Republican frontrunner is correct in saying that former Republican President George W. Bush did not keep the country safe during the 9/11 terrorist attacks.
The fact is, working stiffs with few opportunities and scant education are generally too busy getting by to engage in revolutionary projects to remake society. And history, in fact, shows us that terrorism is generally a bourgeois endeavor.
Hersh's account of the bin Laden raid is a farrago of nonsense that is contravened by a multitude of eyewitness accounts, inconvenient facts, and simple common sense.
Certain Gulf Arabs support proxy jihadist Sunni groups such as al Qaeda's affiliate in Syria, while Iran supports Shia militant forces such as Hezbollah.
Iraqi dictator Saddam Hussein brutally repressed all forms of opposition to his regime, and before the Iraq War, al Qaeda had no presence in Iraq.
The centerpiece of the Bush administration's case for going to war in Iraq was Secretary of State Colin Powell's presentation to the U.N. Security Council on February 5, 2003, six weeks before the invasion.
What is tricky for those hoping to utilize such weapons is that TATP bombs are quite difficult to make because their ingredients, when combined, are highly unstable and can explode easily if mishandled.
Often it is important to listen to what people aren't saying.
Bin Laden comes out of a business background - he studied public administration and economics at university, and he worked for his family company, which was obviously a rather successful enterprise.
In February I secured permission to enter Osama bin Laden's compound in the northern Pakistani city of Abbottabad, where he was killed and where he had lived for the last half-decade of his life; the first, and only, journalist to do so.
Bin Laden's death is just a punctuation point on a set of problems they've had for a long time. I think the prognosis for al-Qaida and groups like it is really bad, and that's a good thing.
Apostasy is a grave crime in Islam and punishable by death in the eyes of members of al Qaeda.
Anwar al-Awlaki was a U.S. citizen by virtue of his birth in Las Cruces, New Mexico, in 1971 while his Yemeni father was studying at New Mexico State University.
Trump displays many of the traits of a proto-fascist, and he is also part of a wave of right-wing nationalist movements that is sweeping the West. He can also be positioned in the long, American right-wing tradition of fearing 'the Other,' whether they are Catholics or Jews or, now, Muslims.
The inattention of the Bush administration to the threat from al Qaeda had results. Shortly before 9/11, Bush's attorney general, John Ashcroft, turned down FBI requests for some 400 additional counterterrorism personnel.
ISIS may be a perversion of Islam, but Islamic it is, just as Christian beliefs about the sanctity of the unborn child explain why some Christian fundamentalists attack abortion clinics and doctors.
Common sense would tell you that the idea that Saudi Arabia was paying for bin Laden's expenses while he was living in Abbottabad is simply risible. Bin Laden's principal goal was the overthrow of the Saudi royal family as a result of which his Saudi citizenship was revoked as far back as 1994.
Seymour Hersh is one of the giants of investigative journalism.
The reason that Islamist militants can assert that jihad is necessary against the perceived enemies of Islam is that there is sufficient ammunition in the Quran to buttress their beliefs. The same could also, of course, be said for the Old Testament, which is full of scenes of violent death visited on the enemies of God.
The rise of ISIS starts with a Jordanian thug named Abu Musab al-Zarqawi who founded ISIS' parent organization, al Qaeda, in Iraq. What gave Zarqawi the opportunity to create al Qaeda in Iraq? It was, of course, George W. Bush's decision to invade Iraq in 2003.
Occasionally, Donald Trump says something that is politically incorrect but which also happens to be true.
And in the end, bin Laden died in a squalid suburban compound surrounded by his wives and children and far from the front lines of his holy war.
I am very suspicious of the notion that somehow bin Laden was a media creation... Bin Laden's actions made him into a big deal. Not the media.
So Pakistan is a country that I'm very fond of and have spent a lot of time, but it is a country where conspiracy theories have a life of their own.
We climbed the stairs to the third floor, where Osama bin Laden died early in the morning of May 2, 2011.
Bin Laden was 200 miles away from the area where all of these drone strikes were taking out his key leaders, he was able to indulge in his hobbies... and he was making occasional video tapes and audio tapes to the wider world.
