Is reggen field theory rendered obsolete byqcd?

We affirm the power of the eikonal approximation in reggeon field theory (rft) and point out its merit as contrasted with renormalization group method for calculating reggeon self-energy correction due to pomeron exchanges. Relative merits ofrft andqcd in appropriate momentum regions of hadronic interactions are also examined to suggest a negative answer to the title.
