We [Afghanistan government] were in the process of cleaning up the government when these attacks happened in the north - not only in Kunduz, but also in other provinces. Our special forces are limited - we cannot be everywhere at the same time and we had to defend every district regardless of how insignificant it might be, because of the very social and political makeup of this country.

We don't have warlords. We have strongmen. They control provinces with military forces. These men at one time controlled territory; they have now been transformed into businessmen and politicians. Today our national security forces are built to control the provinces.

Peace is our goal, but peace from strength, an enduring peace that will bring regional cooperation. What we have emphasized and agreed is that we are strategic partners. We are bound by common interests and will act together to ensure both the safety of United States and the safety of Afghanistan. That is the important consideration. Numbers are a means; they are not an end in themselves.

We will not let the price of peace be greater than the price of war, we will firmly safeguard the achievements of the past 13 years under former President Karzai.

When I first raised the issue of the so-called Islamic State at the Munich Security Conference in February, speaking about its economy, its flexibility and pathology, people thought I was trying to scare them. But now we have experienced just that. If al-Qaida was version 2.0 of terror, then the Islamic State is version 5.0.

Terrorism attacks peoples' trust in the system of their state. There is protection, but only if there is collective action and collective understanding about how to really deal with this phenomenon.

The youth are hurt. Our majority are youth, under 30. They have no hope. They don't get jobs.
