Army Lt. Col. Daniel L. Davis survived the first invasion into Iraq in 1991. He later left active duty and worked for a Texas senator while serving in the Army Reserves. Called back into active duty, he did a tour in Afghanistan (2005-06, another in Iraq, 2008-09), and back to Afghanistan during 2011. During last year's tour, he was part of the Army's Rapid Equipping Tour that took him into every part of the embattled country and enabled him to have "conversations with 250 soldiers in the field." Back in the U.S., he has just issued a blistering report claiming that, despite the deployment of a force exceeding 100,000, there is a glaring "absence of success on virtually every level." He even witnessed Afghan military personnel "collude with the insurgency."
