Description
We re-examine our arguments against the dominance of perturbative QCD over soft, non-perturbative effects in exclusive processes at currently available Q2. We continue to find that perturbative contributions are much smaller than soft contributions (which are capable of explaining the data) in the simple test cases of the pion and nucleon electromagnetic form factors. We see no reason why our results should not generalize, and conclude that there is no justification for the continued application of perturbative QCD to exclusive processes. (orig.)
