  The International Linear Collider is now proposed with a staged machine
design, with the first stage at $\sqrt{s}=250$ GeV and an integrated luminosity
goal of 2 ab${}^{-1}$. One of the questions for the machine design is the
importance of positron polarization. In this report, we review the impact of
positron polarization on the physics goals of the 250 GeV stage of the ILC and
demonstrate that positron polarization has distinct advantages.
