Given that they are only at 135,000 right now due to an extension of the time served by U.S. troops who were supposed to leave Iraq, It seems likely that there will be deployment extensions for additional units scheduled to leave Iraq, as well as an eventual increase in troops intended to deploy to Iraq.
The decision effectively shelves an earlier plan to shrink the size of the US force in Iraq to between 105,000 and 115,000 troops, and will significantly increase the cost of the occupation of Iraq above the Bush administration's previous budget estimates.
