    We obtain the perturbative QCD (PQCD) prediction for the leading twist deuteron form factor, treated as a pair of nucleons in nonrelativistic bound state. It is <10-3 times experiment at Q2=4 GeV2, suggesting that PQCD is not relevant to the deuteron form factor at present values of Q2, or that nonnucleon (e.g., "hidden color") degrees of freedom must be included for a correct description of the deuteron. The tree-level amplitude ∼eg10 and is the sum of several 106 Feynman diagrams, making it an interesting case study in the behavior of perturbation theory.
