>>5553711>Declare war upon them, might as well be forthright.>Do it in the Federal Style, by our power vested in us as President of the FederationI'm going to guess that this is counter officer is a response to the Imperium's ultimatum. The Imperium would have sent its iterators, they would have had with them the full numbers of the fleets troops and planets of the Imperium, the strength of the legions, and the promises that as vassals they would retain their status within society in exchange for tithes and technological access.
They have denied these things, either in ignorance or pride. There is no sense in sending another.
Send the ambassador home in safety to deliver an official declaration of war on behalf of the Federation, just as it was in the days of olde. The Imperium can send its own declaration as well, if it so wishes.
