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 nonperturbative classical configurations, called classicalons, in scatterings like φφ → φφ, can avoid typical acausal divergences. arXiv:1505.07357v4 [hep-th]
