Officials in the George W. Bush administration later criticized the cruise missile strikes that were ordered by President Bill Clinton in Afghanistan in 1998 as only 'pounding sand.'

The Green Berets of U.S. Special Forces 5th Group - known as 'the Legion' - who led the anti-Taliban campaign represent a textbook case of a successful Special Forces campaign.
The documentary feature film 'Legion of Brothers' tells the stories of the handful of U.S. Special Forces soldiers who, shortly after the 9/11 attacks, went into Taliban-controlled Afghanistan and, within a matter of weeks, overthrew the Taliban regime.
When ISIS and al Qaeda have attacked or plotted attacks in the West in the past decade or so, they have invariably used hydrogen peroxide-based bombs because acquiring military-grade explosives or dynamite is nearly impossible for would-be terrorists in Western countries.
Again and again since 9/11, terror attacks in the West have been carried out by second-generation Muslims who are citizens of the very country they are attacking.
Mateen pledged allegiance to ISIS during his attack, the worst terror attack on American soil since 9/11.
The sitting prime minister, Jose Aznar, who had strongly backed the U.S.-led Iraq War, was unseated by a challenger who then pulled Spanish troops out of Iraq. The Madrid terrorist attacks are generally regarded as being the key to why Aznar, who had been leading in the polls, was defeated.
Because of the 9/11 attacks, the framing of terrorism by politicians, the media, and the public too often in the past decade and a half has been that it is Islamist political violence that is the terrorism we need to be concerned about.
There are all sorts of despicable people who journalists have done interviews with, and it's been useful. Isn't more information better than less information?
Abu Musab al-Suri is someone I got to know pretty well because he's a Syrian. Very bright guy, lived in London. He actually was the person who took myself and correspondent Peter Arnett and the cameraman, Peter Juvenal, to interview bin Laden for his first TV interview.
One of the themes of 'The Longest War,' my book, which came out before the Arab spring happened, was how al-Qaida and bin Laden was losing the war of ideas in the Muslim world, not because the United States was winning them, but because al-Qaida was simply losing them.
Incompetence is a better explanation than conspiracy in most human activity.
If the Arab Spring was a large nail in the coffin of al-Qaeda's ideology, the death of bin Laden was an equally large nail in the coffin of al-Qaeda the organization.
ISIS is even at war with its most natural ally, al Qaeda in Syria.
Since Snowden went public, companies such as Apple and Google - two of the world's most valuable companies - have incorporated much greater encryption into their products and have also been at pains to show that they will not go along with U.S. government demands to access their encrypted products.
In picking Gen. Jim Mattis for Defense secretary, President-elect Donald Trump has said that he found his 'Gen. George Patton.' Yet that label may not really capture what makes Mattis a distinctive choice.
How can you prevent an attack by returning foreign fighters if you are not cognizant of their names and links to ISIS?
It is in American and Afghan interests for the U.S. to stay in Afghanistan so it doesn't turn into Iraq circa 2014, with the Taliban controlling much of the country while hosting a strong presence of ISIS and al-Qaeda as well as every other jihadist group of note.
In mid-November 2001, as they moved toward the city of Kandahar, the Taliban's de facto capital in southern Afghanistan, Amerine's team called in airstrikes against advancing Taliban units and more or less obliterated a Taliban column of a thousand men that had been dispatched from Kandahar. It was the Taliban's final play to remain in power.
Candidate Trump had previously opined that 'Islam hates us' and had called for 'the total and complete shutdown of Muslims entering the United States,' an argument he has since modified and moderated.
Hydrogen peroxide-based bombs were used in the London bombings in 2005; in al Qaeda's foiled plot to attack subways in New York City in 2009 and also in the ISIS-directed Paris attacks in 2015 and the ISIS-directed attacks in Brussels a year later.
Because 9/11 was carried out by 19 foreign-born Arab hijackers, many assume that all terrorists who attack the West are foreigners.
In late May 2016, an ISIS spokesman called for attacks in the West during the month of Ramadan.
Will there be a political backlash against British Prime Minister Theresa May, whose ruling Conservative Party is traditionally seen as 'stronger' on terrorism than its main rival, the Labour Party?
The reason that attacks by American terrorists who are not jihadist militants are sometimes not called 'terrorism' is, in part, because in the United States, terrorism is a crime which has to be in some way be associated with a 'designated' terrorist group such as ISIS.
If a parent knows that their kid is suddenly becoming infatuated with ISIS, they face a very difficult choice, which is, you know, do I - what do I do?
9/11 was a sort of hinge event in American history, and all jihadi terrorist plots or attacks are kind of filtered through that lens.
Sanctions on Pakistan have been part of the troubled U.S.-Pakistan relationship in the past and should not be considered as an option in the future.
The money that bin Laden inherited was about 20 million dollars over the course of many years, not the much larger sums some have suggested. In 1994, his family cut him off.
Bin Laden was intelligent, well-informed, and low key. The people around him treated him with great deference, calling him 'sheikh,' a term of respect.
Adding to your list of enemies is never a sound strategy, yet ISIS' ferocious campaign against the Shia, Kurds, Yazidis, Christians, and Muslims who don't precisely share its views has united every ethnic and religious group in Syria and Iraq against them.
Investigations by special prosecutors can take on a life of their own.
It's hard to imagine any Muslim fessing up to their secret proclivity for Sharia law knowing they would be deported if they gave the wrong answer.
The less the ISIS 'caliphate' exists as a physical entity, the less the group can claim it is the 'Islamic State' that it purports to be.
A decade and a half ago, the U.S. Air Force dropped massive 15,000-pound 'Daisy Cutter' bombs on the Tora Bora complex where Osama bin Laden was hiding in December 2001.
In the public's mind, Special Forces are often confused with the 'door kickers' of Special Operations Forces - such as SEAL Team 6 and Delta Force - who are the United States' elite counterterrorism operators.
In one notorious episode in 2002, in the holy city of Mecca, the religious police prevented girls from fleeing a school that was on fire because they were not properly dressed.
Abedi appears to be one of the many thousands of Western Muslims who have embraced militant Islam, often as a way of trying to resolve the tension between their split identities.
Security services, from Afghanistan to the United States, should be alert throughout the Ramadan period, but especially on the 27th day of the holy month.
The hard reality is that attacks by vehicles in public places are very hard to defend against in a free and open society. The best defense against such attacks is good intelligence, and that often comes from inside the Muslim community.
Typically, terrorist attacks produce a rally-around-the flag effect as was the case after 9/11 and the huge outpouring of public support that then-President George W. Bush garnered.
The commonly accepted definition of terrorism is that it is politically motivated violence directed at civilians by entities other than a state. These kind of attacks can come from the far right, the far left, racists of every stripe, as well as jihadists.
It's much harder to detect a lone wolf than it is somebody who's associated with a larger organization who's having planning meetings and making phone calls to people in the organization. And so that is really how the jihad has really developed in the United States.
The thing that's very puzzling to somebody who's been in Pakistan repeatedly since 1983 is lots of people live in compounds with high walls in Pakistan. I mean, that's so completely routine. In fact, you know, it would be un-routine to have the reverse.
Bin Laden studied economics and public administration before he turned to a life of jihad.
It is hard to imagine two more final endings to the 'war on terror' than the popular revolts against the authoritarian regimes in the Middle East and the death of bin Laden.
The Nazis and the Khmer Rouge went to great lengths to hide their crimes against humanity. Instead, ISIS posts its many crimes on social media for global distribution with seemingly no thoughts for the consequences.
ISIS' key social media-encrypted platform is Telegram, which is engineered by a Berlin-based tech company that can simply ignore the rulings of American federal judges as well as legislation passed by the U.S. Congress.
Mattis has been sharply critical of President Barack Obama's policies on Iran and Obama's capping of troop numbers and campaign end-dates in theaters of war such as Afghanistan and Iraq. Mattis also appears to be a skeptic of the Obama-era policy of putting women into combat roles.
Nothing is more powerful than hearing from former members of the group that ISIS is not creating an Islamist utopia in the areas it controls, but a hell on earth.
