Dan McNeill is a retired general in the United States Army, who commanded the NATO International Security Assistance Force in Afghanistan between February 2007 and June 2008, being replaced by GEN David McKiernan. His prior assignment was heading United States Army Forces Command. He is now the senior military analyst at Human Rights Watch, and has served in the Department of Defense senior mentor program.
Returning in 2007, he took command from British General Sir David Richards; he was the first four-star American officer to be assigned to Afghanistan.
As a lieutenant general, he took command of Combined Joint Task Force 180 in Afghanistan in late 2001. During this period, he also launched an investigation, in December 2002, into deaths resulting from American interrogation of detainees.
Against George W. Bush Administration policy, he made a public statement that “US forces acknowledge the internationally recognized boundaries of Afghanistan, but may pursue attackers who attempted to escape into Pakistan to evade capture or retaliation.” In 2007, he denied Administration charges that Iran was actively supporting the Taliban.
