  Scattering amplitudes of partons in QCD contain infrared divergences which
can be resummed to all orders in terms of an anomalous dimension.
Independently, in the limit of high-energy forward scattering, large logarithms
of the energy can be resummed using Balitsky-Fadin-Kuraev-Lipatov theory. We
use the latter to analyze the infrared-singular part of amplitudes to all
orders in perturbation theory and to next-to-leading-logarithm accuracy in the
high-energy limit, resumming the two-Reggeon contribution. Remarkably, we find
a closed form for the infrared-singular part, predicting the Regge limit of the
soft anomalous dimension to any loop order.
