A properly lead Core would never do something as stupid as commit acts of war against big daddy Liberty. However, with the disbandment of the "board" (OF), the Core could be construed as currently being a headless chicken with little unified direction. A number of internal groups may be vying with each other to fill the power vacuum left behind, leading to all kinds of disorganized nonsense and ill-informed decisions.
As far as I'm concerned, occurrences like these should not be entirely ignored by canon. Something interesting could be made of this.
