50,000 more US troops can save Iraq - Keegan

President George W. Bush is about to launch a final push in Iraq with a large reinforcement of American troops in the hope of crushing the insurgency before America embarks on a large-scale withdrawal of force from the country.
The size of the force is commonly set at about 40,000-50,000 troops. The aim of this surge will be to inflict severe damage and loss on the problem-making elements within Iraq, including both Shia and Sunni militias, and to increase training of the Iraqi security forces under American supervision.
