""Successful transition efforts demonstrate
that reentry of U.S. forces into Iraq in an advisory and long-term presence
would afford an increased opportunity for enduring freedom in Iraq. As depicted
in Figure 3, the trajectory, for a longterm U.S. presence, if implemented, would
be beneficial for Iraq and the region, especially given the instability and
rising potential nuclear threat in Iran. Large troop concentrations are not
necessarily the solution, as the United States has used a much smaller footprint
effectively in Kuwait to provide a satisfactory security transition in contrast
to larger troop levels for the sustained U.S. presence in Germany, Japan, and
Korea.""
