tl;dr: The North Atlantic Defense Coalition activates the GUARD Treaty and declares war on Non Grata in defense of it's ally TTK.
Signed,
Dark Wizard, Secretary General
and
The Assembly of the North Atlantic Defense Coalition
EDIT: I don't consider this an oA, I consider this NG didn't have the stones to hit TTK in their quest for Maroon domination. You declare war on Maroon, you declare war on TTK. Fancy how our treaty covers oA's too though!
