We reassess the claim by the NuTeV Collaboration of a three standard deviation disagreement from the Standard Model in the value of the Weinberg angle determined in neutrino-nucleus deep-inelastic scattering. The recent discovery of an iso-vector EMC effect, combined with strong theoretical constraints on charge symmetry violation lead us to the conclusion that the Standard Model still lives. We pay particular attention to the open questions which if resolved could further improve the precision of such tests.
