In the 101st Airborne Division headquarters in Mosul, we had a sign on the wall. It was a question that we would ask ourselves before every new operation or policy initiative. It asked: Will this policy or operation take more bad guys off the streets than it creates by its conduct?
Leading the coalition military effort during the surge in Iraq in 2007 and 2008 was the most important endeavor - and greatest challenge - of my 37 years in uniform.
We're here so that Afghanistan does not once again become a sanctuary for transnational extremists the way it was when al-Qaeda planned the 9/11 attacks in the Kandahar area, conducted the initial training for the attackers in training camps in Afghanistan before they moved on to Germany and then to U.S. flight schools.
Mubarak would meet with me when I was at Central Command. He would lean and put his hand on my knee, as if a father figure, and say, 'General, don't ever forget the Arab Street. Listen to the Arab Street.' I'd like to go to him now and say, 'Mr. President, what about that Arab Street, what's that all about?'
In many respects, Afghanistan represents a more difficult problem set. It does not have a number of the blessings that Iraq has in terms of the oil, gas, land of two rivers, the human capital that Iraq built up over the years, the muscle memory of a strong government - albeit one that was corrupted over time.
When Western politicians propose blanket discrimination against Islam, they bolster the terrorists' propaganda.
I think carpet bombing is an absolutely tremendous idea if the enemy accommodates you by laying himself out like a carpet in the middle of the desert without any civilians or infrastructure around him. Sadly, the Islamic State has learned that that is a losing proposition and does not accommodate us in that way.
Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters - all connected to the next-generation internet using abundant, low-cost, and high-power computing.
The Congress, the executive branch, and our fellow citizens have done an enormous amount to support our troopers and their loved ones. And all of us are grateful for that.
I had the privilege of serving in uniform with British forces in Cold War Europe, Bosnia, Iraq, Afghanistan, and the greater Middle East.
Leadership is an individual sport, one that has to be fine-tuned to each of the people that reports to you. Leaders also need to provide the direction, energy, encouragement and inspiration for each person who reports directly to the leader as well as for the overall organization.
The Germans have done wonderful work. Not long ago, a German battle group battalion conducted a very impressive counterinsurgency operation in a portion of Baghlan province. I think these are the first counterinsurgency operations conducted by any German element after World War II. And they did a very impressive job.
There is no question in my mind that a 'Brexit' would deal a significant blow to the E.U.'s strength and resilience at exactly the moment when the West is under attack from multiple directions.
In all of our efforts, we continue to emphasize the importance of inclusivity and transparency on the part of the Afghan government and leadership, especially in linking nascent local governing institutions to the decision-making and financial resources in Kabul.
Reconciliation is what takes place, of course, at higher levels. President Karzai has been very clear about the red lines for reconciliation, accept the constitution, lay down their weapons, cut their ties with al Qaeda and essentially become productive or at least participating members of society in that regard.
