In 2005, Casey was hopeful that the December 2005 Iraqi elections could lead to a more unified and moderate Iraq which—in conjunction with the training of Iraqi security forces—could pave the way for U.S. troop reductions in early 2006. In August 2005, Casey used specific troop numbers in his public discussion of a possible drawdown. He said the troop level of 138,000 could be reduced by 30,000 in the early months of 2006 as Iraqi security forces took on a greater role. President George W. Bush publicly called the talk "speculation" and rebuked the general. The bombing of the al-Askari Mosque, a sacred Shia religious site in Samarra, is believed to have stoked sectarian tensions and derailed coalition plans to speedily transfer significant security responsibility to the Iraqi government by the end of 2006.
