  We argue that in QCD, the Debye mass requires not only a mathematical
definition but also a physical one and temporal axial gauge could provide for a
physical screening potential for this purpose. Unfortunately, this gauge is
spoiled by problem of energy conservation rather than the well known divergence
due to the double pole in the longitudinal propagator. We also show that KMS
condition is violated in this gauge and is therefore not universally true.
