Edit: About the Gallic stance towards the citizens of Sirius, you can find it in this thread.
"Meeting these demands, they say, would result in granting the people of Bretonia full political and economical freedoms including permission to elect the planetary Parliaments and local bodies of power. Refusing to submit would be considered a declaration of war that would result in the installation of the aforementioned regime by force. Even in the latter case, no sanctions or rights limitations would be imposed upon the citizens of Bretonia that do not participate in the resistance."
