Even though approximated, strong coupling non-perturbative QCD amplitudes
remain very difficult to obtain. In this article, in eikonal and quenched
approximations, physical insights are presented that rely on the
newly-discovered property of Effective Locality.Comment: Revised version (28 pages and 1 figure in REVTeX). Follow-up work of
