Pentagon on Tuesday alerted more than 35,000 Army soldiers that they could be sent to Iraq this fall. In Congress, House Democrats defiantly pushed a plan to limit war funding to two-month installments. The deployment orders signed by Defense Secretary Robert Gates would allow commanders to maintain the buildup of troops through the end of the year if needed, the Associated Press reported. President George W. Bush has ordered nearly 30,000 additional troops to Iraq to quell a spike in violence, particularly in and around Baghdad. There are currently about 146,000 U.S. troops in Iraq. Pentagon spokesman Bryan Whitman said the orders do not mean the military has decided to maintain the increased force levels through December. The Pentagon "has been very clear that a decision about the duration of the surge will depend on conditions on the ground," he said.
