"In the months leading up to the invasion, a debate over troop levels required in Iraq had been privately brewing between the military leadership and Donald Rumsfeld. Rumsfeld and his deputy, Paul Wolfowitz, believed that a force of under 100,000 troops would be sufficient for the invasion and occupation of Iraq. A month before the invasion, the fight over troop levels became public, as the chief of staff of the Army, Eric Shinseki, testified before the Senate Armed Services Committee, ignoring pressure from Rumsfeld and Wolfowitz."
