  We suggest that classicalization can cure non-local quantum field theories
from acausal divergences in scattering amplitudes, restoring unitarity and
causality. In particular, in "trans-non-local" limit, the formation of
non-perturbative classical configurations, called {\it classicalons}, in
scatterings like $\phi\phi\rightarrow \phi\phi$, can avoid typical acausal
divergences.
