Historian: The revolutionary party has been accused of having many overambitious goals and of having caused great suffering. However, most of the party' s goals were quickly achieved and the party did not have enough power to cause the suffering the critics claim it caused. So it is clear that the party was not overambitious and caused no suffering. The reasoning in the historian's argument is flawed because the argument ['fails to establish that the revolutionary party caused no suffering', "provides no evidence that the revolutionary party's goals were not overambitious", "fails to establish that any of the revolutionary party's critics underestimated the party's power", 'gives mutually inconsistent responses to the two criticisms']
