Lattice QCD is making good progress toward calculating the structure and properties of light
nuclei and the forces between nucleons. These calculations will ultimately refine the nuclear
forces, particularly in the three- and four-nucleon sector and the short-distance interactions of
nucleons with electroweak currents, and allow for a reduction of uncertainties in nuclear manybody
calculations of nuclei and their reactions. After highlighting their importance, particularly to
the Nuclear Physics and High-Energy Physics experimental programs, I will discuss the progress
that has been made toward achieving these goals and the challenges that remain.
