How could not not add the IRS?
Round two is cutting income taxes to a flat rate of 10%-15%.
Round three would be cutting the waste out of other, necessary depts like the Dept of Defense and the Dept of the Treasury (where the IRS resides). The Dept of Defense should be strong with up-to-date research and development and cutting-edge technology. Depts like the IRS should be tiny little non-threatening depts that carry out the fiscal functions of a small, benign federal government.
