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.
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.
Anne Richard, a senior U.S. State Department official, testified at a Senate Homeland Security Committee hearing in November 2015 that any Syrian refugee trying to get into the United States is scrutinized by officials from the National Counterterrorism Center, FBI, Department of Homeland Security, State Department and Pentagon.
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.
Trump himself has not laid out a clear agenda on the national security issues that are the most pressing for the United States, from the resurgence of the Taliban in Afghanistan to the deepening Syrian civil war to the fight against ISIS in Iraq and Syria and the flexing of Russian muscles under President Vladimir Putin.
I was the only outsider to visit the Abbottabad compound where bin Laden lived before the Pakistani military demolished it.
ISIS despises the Russian government for its support of the Syrian dictator Bashar al-Assad, and so it's no surprise that ISIS began targeting Russia in 2015, around the same time that Russia first intervened in the Syrian civil war.
Both China and Russia felt duped by the U.N. 'no-fly' zone resolution regarding Libya in 2011 that eventually led to the ouster of Libyan dictator Moammar Gadhafi. China and Russia had abstained from the Libyan resolution, and neither country plans to make what they regard as a similar mistake again.
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.
European countries simply do not have the ideological framework the United States has in the shape of the 'American dream' that has helped to absorb successfully wave after wave of immigration to the States, including Muslim Americans who are well integrated into American society. There is no analogous French dream or German dream.
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.
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.
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.
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.
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.
Osama bin Laden fervently hoped that attacking the United States would create pressure on American leaders to reduce their support for Middle Eastern regimes. Bin Laden believed that without that American support, the Arab regimes would collapse and would be replaced by Taliban-style rulers.
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.
A little exposure to a city like Sulaimani will help Trump understand that the Middle East is a much more complex place than he seems to believe. Perhaps Trump could even give a speech at the American University in Sulaimani, just as President Obama did at Cairo University early in his first term.
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.
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.
