Should the UPF be a Confederation?

For those who don't know, a confederation is a <i>&quot;union of political units for common action in relation to other units. Usually created by treaty but often later adopting a common constitution, confederations tend to be established for dealing with critical issues (such as defense, foreign affairs, or a common currency), with the central government being required to provide support for all members.&quot;</i> — (from <i><b>Wikipedia</b></i>)<br /><br />While the the United Planetary Federation is: <i>&quot;the extra-national organization that protects the Frontier Sector from outside aggression, and functions as a forum for resolving altercations between its member planets.&quot;</i> — (from the <i><b>Star Frontiers Wiki</b></i>)<br /><br />...or more conically: <i>&quot;As the danger increased, the Humans, Dralasites, Vrusk and Yazirians formed the United Planetary Federation (UPF) to defend their worlds.&quot;</i> — (from the <i><b>Alpha Dawn</b></i> rules)<br /><br />As the UPF was established to to deal with an external threat, after the First Sathar War, should the organization be rightfully be called the United Planetary Confederation, aka, the UPC?
