On February 25, 2003, the Chief of Staff of the Army, testified in front of the Republican-controlled Congress that it would take up to 300,000 soldiers to occupy and stabilize Iraq in the event of war.
Republican Party leaders George Bush, Denny Hastert (Speaker of the House), Bill Frist (Senate Majority Leader) and Don Rumsfeld (Secretary of Defense) decided that, politically, it was not feasible to send that many troops to Iraq. Why, the cost, sending 300,000 troops to Iraq would imperil their precious tax cut. To the Republican Party, the tax cut was more important to them than doing the job right in Iraq. They figured the tax cut would be politically feasible only by sending 150,000 troops to Iraq.
