Did the Federation council formally declare war upon the Dominion? Or is it part of Star Fleet's standing rules of engagement to begin, prosecute and end major wars on their own? At some point did the ambassadors/delegates/representatives from all the member worlds meet in full session with the President (and Prime Minister?) in attendance. Was there a impassioned speech by the President, followed by a debate and a vote to declare that a state of war existed between the United Federation of Planets and the Dominion? Or is a formal declaration of war this charming old custom from Earth's past that is no longer observed? There doesn't seem to have been any way for the Federation to send a notification of such a declaration to the Founders. What do you think?
