Iraq's interim president said Tuesday it would be "complete nonsense" to ask U.S. and other foreign troops to leave Iraq at this point but some of the 170,000 soldiers could be leaving Iraq by the end of the year. "It's only complete nonsense to ask the troops to leave in this chaos and this vacuum of power," President Ghazi al-Yawer told reporters. He said foreign troops should leave only after Iraq's security forces are built up, the country's security situation has improved and some pockets of terrorists are eliminated. "By the end of this year, we could see the number of foreign troops decreasing," al-Yawer said.
