Declassified Key Judgments of the National Intelligence Estimate “Trends in Global Terrorism: Implications for the United States” dated April 2006
(All paragraphs Including the word "Iraq"):
We assess that the Iraq jihad is shaping a new generation of terrorist leaders and operatives; perceived jihadist success there would inspire more fighters to continue the struggle elsewhere.
The Iraq conflict has become the “cause celebre” for jihadists, breeding a deep resentment of US involvement in the Muslim world and cultivating supporters for the global jihadist movement. Should jihadists leaving Iraq perceive themselves, and be perceived, to have failed, we judge fewer fighters will be inspired to carry on the fight.
Four underlying factors are fueling the spread of the jihadist movement: (1) Entrenched grievances, such as corruption, injustice, and fear of Western domination, leading to anger, humiliation, and a sense of powerlessness;
(2) the Iraq “jihad;” (3) the slow pace of real and sustained economic, social, and political reforms in many Muslim majority nations; and (4) pervasive anti-US sentiment among most Muslims—all of which jihadists exploit.
Al-Qa’ida, now merged with Abu Mus’ab al-Zarqawi’s network, is exploiting the
situation in Iraq to attract new recruits and donors and to maintain its leadership role.
Fighters with experience in Iraq are a potential source of leadership for jihadists pursuing these tactics.
The increased role of Iraqis in managing the operations of al-Qa’ida in Iraq might
lead veteran foreign jihadists to focus their efforts on external operations.
