How can it NOT be a national liberation movement? You declared independence and are trying to expell the Xyraelis! Dispite the reasonings behind it, it's quite obvious that it's a national liberation movement. So nothing has changed Xyrael from bringing up a good and valid point.
I have yet to see any evidence of any of what you claim happening. For this reason, Collosea is still supporting the proposal of sending observers to the revolting Xyraeli territories.
