  In this paper various predictions for the scaling exponents of the Nonlocal
Kardar-Parisi-Zhang (NKPZ) equation are discussed. I use the Self-Consistent
Expansion (SCE), and obtain results that are quite different from result
obtained in the past, using Dynamic Renormalization Group analysis (DRG), a
Scaling Approach (SA) and a self-consistent Mode Coupling approach (MC). It is
shown that the results obtained using SCE recover an exact result for a
subfamily of the NKPZ models in one dimension, while all the other methods fail
to do so. It is also shown that the SCE result is the only one that is
compatible with simple observations on the dependence of the dynamic exponent
$z$ in the NKPZ model on the exponent $\rho$ characterizing the decay of the
nonlinear interaction. The reasons for the failure of other methods to deal
with NKPZ are also discussed.
