  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.
