wisdom. John Clute comments in The Encyclopedia of Science Fiction that a pattern running through the works of Williamson is a fight to maintain freedom against external enemies with the heroes adhering to libertarian principles. Clute notes the frequent presence of female heroes in Williamson's works and feminist critic Liz Bourke describes Williamson's treatment of female characters as "less clearly marginalizing" than that of John Ringo and Tom Kratman. Blair Nicholson, in a doctoral thesis from the University of Waikato, points out commonalities in the authorial stances of Williamson and David Weber who both emphasize that in military science fiction, the hypothesized military environment must be depicted in realistic detail down to details of strategy and tactics. According to Williamson the work should then seek to "explore the proposed system, and its interactions with the people – soldiers and civilians – involved". Nicholson notes that Williamson depicts the United Nations as an enemy, and particularly so in his Freehold (2004) novel, where the United Nations appears as an authoritarian oppressor. This depiction of the United Nations has parallels in the Marine in Space series by Ian Douglas and in the works of Tom Kratman and is reflective of a negative right-wing popular opinion on the institution.
