Phillip Green Colonel Phillip Green was a despotic militia leader on Earth in the 21st century during World War III . Green , known for his motto : " " Overwhelm and devastate , " " was notorious for striking at his enemies during treaty negotiations . ( ) During the war , Green led a faction of violent eco - terrorists whose actions led to the death of some thirty - seven million people . ( , " " ) Barely three years after a cease - fire had ended the war , he ordered the euthanasia of hundreds of thousands of radiation - sickened Human s so they would not pass on mutations to future generations . Green outlined his rationale by speaking to a crowd about how they must " " reject the impure and cast it out . " " This act was met with mixed feelings by survivors , many regarding him as nothing more than a genocidal madman . Others saw him as a pragmatic visionary who " humanely " euthanized radiation - afflicted individuals , preventing those afflicted and their descendants from passing on deadly mutations and the suffering that would come with that . ( ) This controversial and contentious posthumous view of Green resulted in heated debates about him and the impact of his policies for many years ; among the students of Green ' s teachings , years afterward , John Frederick Paxton made use of his ideologies to lead a group known as Terra Prime in an unsuccessful bid to expel all non - Humans from the Sol system in 2155 . ( ) A replication of Green was created by the Excalbian s in 2269 . This duplication formed part of their study of the nature of the Human concepts of " good " and " evil . " ( ) In 2364 , an illustration of Colonel Green inexplicably appeared when Data was assimilating the Dixon Hill novels aboard the . ( ) Memorable quotes . " " Overwhelm and devastate . " " " " This is not a time for timidity and second guessing . We cannot afford to doubt ourselves . " " " " To be Human is to be pure . " " " " I have no quarrel with you , any more than you have with me ! " " ( Excalbian duplicate ) " " Men don ' t talk peace unless they ' re ready to back it up with war . " " ( Excalbian duplicate ) " " History tends to exaggerate . " " ( Excalbian duplicate ) Background information . Green was portrayed by actor Phillip Pine in " The Savage Curtain " and by Steve Rankin in " Demons " . This character ' s surname was formatted " Green " in the script of " The Savage Curtain " , and in a graphic that appears in . However , the name was spelled " Greene " in the final draft script of " Demons " . In the , his surname was Green . Green ' s first name was given as " Phillip " in the aforementioned obscure graphic from . The name was likely chosen in reference to the first name of the character ' s original actor , Phillip Pine . ( " Encyclopedia " 4th ed . , vol . 1 , p . 318 ) The uniform worn by Steve Rankin in " Demons " was previously worn by a Mokra Order soldier in the episode , by a Kradin in the episode , and by Steve Blalock in the " Enterprise " episode . It was sold off on the It ' s A Wrap ! sale and auction on eBay . FASA ' s RPG sourcebook " The Federation " gave his full name as Edward Featherstone Green . First appearance . Gene Roddenberry conceived of Green as " Mr . Green , who was something of a U . S . ' Hitler - racist ' in the late 20th Century . " Roddenberry described the character in this way in an initial story outline for " The Savage Curtain " , which he wrote on . ( " " ) Imagining how Green might have been conceived , Manny Coto commented , " " There ' s so much history that has been hit upon in the original series all the way through " " , and touched on in characters that are mentioned , like Colonel Green , and things like that , that are just kind of dropped in . And you know they ' re just dropped in by writers on a weekend , [ . . . ] you know , who are just like , ' Ah . . . ' Gene Coon is just like , ' Oh , Colonel . . . Okay , we ' ll call him Colonel Green . " " ( " Before Her Time : Decommissioning " Enterprise " , Part One : New Voices " , ENT Season 4 Blu - ray special features ) A " Star Trek " fan himself , Phillip Pine was delighted to receive the role of Green , play the part , and be associated with it . " " The character of Green was well written , " " he remarked . " " There were little or no changes required by the director , Herschel Daugherty , or myself to highlight Green ' s Machiavellian mind . Adolf Hitler was discussed at one point and I was certainly influenced by that man ' s character in playing the role . " " ( " " # 130 , p . 76 ) The tone in which he addressed Surak as " . . . Vulcan ! " in the episode may have been some insight into Green ' s xenophobic attitude towards alien s . Green proved extremely popular . Although Phillip Pine played many villains in television productions , he found Green to be the most often recognized . " " I think Colonel Green is probably well - remembered because he was such an unmitigated bastard , " " Pine mused . " " He had no redeeming qualities at all ; none . The guy ' s smile was even sinister ! He probably had bad teeth and they hurt . Everything about him was bad [ . . . ] My grandson told me that I should get a red jumpsuit [ like he wears in ' The Savage Curtain ' ] ! " " ( " Starburst " Special # 29 , pp . 59 & 62 ) One fan of Green was Manny Coto . " " For some reason , I have a fetish for Colonel Green , " " he laughed . " " I can ' t describe it . I ' ve always found him a fascinating character , because it ' s this dark . . . It was like a Hitler . You know , in the original series , when they mention Colonel Green , it was like , ooh , the Federation had a Hitler in it . That ' s fascinating . " " ( " Before Her Time : Decommissioning " Enterprise " , Part Two : Memorable Voyages " , ENT Season 4 Blu - ray special features ) Reappearance . Originally , Manny Coto intended to use Green as a villain in the Augment s trilogy in season four of . While working on the story , he said , " " I want to do a very harrowing ' Colonel Green ' arc . I ' m determined to get ' Colonel Green ' into this show . " " Coto also thought Green fit well into the plot with the Augments , later admitting , " " I always thought that he was an interesting character to bring to life and flesh out . But the implication was that he had something to do with the Eugenics Wars as well . " " Coto invented an extensive backstory for the character ' s appearance on " Star Trek : Enterprise " . " " It was fun fleshing him out and creating a whole history , a background for him in these episodes , " " said Coto . After he learned that Brent Spiner was interested in a role on the series , Coto changed the story arc to accommodate Spiner . " " For a little while , " " Coto explained , " " I even toyed with the idea of him playing Colonel Green . " " Coto instead created the character of Arik Soong for Spiner to play . Coto also considered Green being portrayed by Peter Weller , though he went on to instead appear as John Frederick Paxton in fourth season two - parter and . ( " Terra Prime " audio commentary ) Green was featured in devised by Garfield and Judith Reeves - Stevens , also intended for the series ' fourth season . In that narrative , Green was linked to an extremist political movement called the Optimum ( which the Reeves - Stevenses took from their novel " " ) . A heretofore secret connection between Green and Malcolm Reed ' s great - grandfather would have been established in the story . ( audio commentary , ENT Season 4 Blu - ray special features ) Also , Green ' s appearance in the undeveloped episode would have linked him to an emblem previously shown on a World War III uniform worn by Q in , here used as Green ' s personal command emblem . A flag featuring the emblem was produced for , with the hope that it could be reused , but this never came to pass . The final draft script of " Demons " commented , " " Greene is a classic firebrand , a boldly powerful speaker . " " By then saying , " " The scene has a " Triumph of the Will " quality to it , " " the script indicated that Green was to seem like a Nazi leader . As Green was to be represented only on a monitor in " Demons " , the casting of the part for that reappearance took place after production on the episode wrapped . The role had to be recast because Phillip Pine had died since appearing in " The Savage Curtain " . To adopt the part , Steve Rankin underwent several physical changes . " " They made me up , got my hair dark , gave me the pointy sideburns , " " he said . Like Pine before him , Rankin was also thrilled to portray Green , having been a " Star Trek " fan too . " " That was a very , very cool thing to do , " " he enthused , adding , " " but Col . Green was one of the worst men in the universe . " "
