This critique fails miserably becuase they dont attack anything fundamental in Just war theory. The only thing it attacks is the idea that you must get permission of a “proper authority”, he sayd that the choice to go to war should be democratic.
Its a good read, and youll also get some really “good” (scary actually)quotes from Saint Augustine.
Thomas Aquinas (1225-1274) codified Augustine’s reflections into the distinct criteria that remain the basis of Just War Theory as it is used today. The need by a civil society to provide sound justification for going to war is one of the many practical influences that Philosophy has on our lives. — Just War Theory - Oregon State University
