Sadr City, the truce is based on the fact the USA troops will not attend to security issues. The longer the USA deployments continue, the greater the risk for returning violence.
One might ask, why aren't the USA troops welcome?
US: 500 youths detained in Iraq; 10 in Afghanistan
Associated Press - May 19, 2008 5:43 AM ET
NEW YORK (AP) - The U.S. military is holding about 500 juveniles suspected of being "unlawful enemy combatants" in detention centers in Iraq.
A total of 2,500 youths under the age of 18 have been detained for periods of up to a year or more since President Bush's anti-terrorism campaign began in 2002. Almost all those who have been detained are in Iraq. About 10 are currently being held in Afghanistan.
The disclosure has been made by the United States to a U.N. committee on children.
The ACLU and other civil liberties groups have denounced the practice as abhorrent. And they say it's in violation of U.S. treaty obligations.
