  At the colliders RHIC and LHC, nuclei at the ultrarelativistic energies of
$100$ GeV/A and $2.7$ TeV/A will be smashed together with the hope of creating
an elusive and short-lived state of matter called the quark gluon plasma. The
initial conditions which determine the dynamical evolution of the quark gluon
matter formed in the central region after the collision depend crucially on the
small $x$ component of the nuclear wavefunction before the collision. In this
comment, we discuss recent work which argues that, for large nuclei, weak
coupling techniques in QCD can be used to calculate the distribution of these
small $x$, or wee, partons. The ramifications of this approach for the dynamics
of heavy ion collisions and the various signatures of a quark gluon phase of
matter are discussed.
