Right now, the world need to be united.
Fighting against each other in this moment is detrimental to the world.
Even Pandemonium acknowledges this and so if any of the great power wanted to wage war against the other, most of the other world power would discourage such type of behavior and instead bringing them into the negotiation table to talk it out and find a compromise with each other.
Secret battles and secret wars of course still happens but at least large scale war had dropped since the creation of the World Council headed by the Seven Great Powers.
All of this is because each member could at least negotiate things.
But if the World Government allies with Pandemonium, then any proposal or any new act that is about to be proposed is already ninety percent pass.
One hundred percent if Katarina sat back on her position of the High Chancellor. Everyone could see this and everyone is uneasy.
