"Star Trek: Enterprise was the first Trek series to appear after 9/11, and reflected these new realities. The prequel series crew stumbled as they confronted all manner of unfamiliar civilizations, and did not even get along with the Vulcans very well. Then, in season three a 9/11-style attack on Earth forced Starfleet to launch an expedition to go after the shadowy Xindi, who had launched the strike. Making the Xindi potentially scary was the consortium nature of their alliance, including humanoid, arboreal, insectoid and aquatic species. Just as al Qaeda was an international terrorist consortium, the Xindi was more dangerous together than separately — a fact the Enterprise crew use to pry away some of the species from the organization."
