 The Canadian economist Jacob Viner called Mantoux's book an "extremely searching criticism" and "detailed economic critique" of Keynes that demonstrated "with the benefit of hindsight" that Keynes' political and economic judgments were unsound.René Albrecht-Carrié agreed with Mantoux's argument that Germany could have paid reparations, although he doubted the political feasibility of extracting them from Germany.He also claimed that Mantoux "ruthlessly exposed" the "loose and fallacious thinking of Keynes and others"
