I've recently finished my somewhat almost nearly quite unfinished political factbook, which I saw as a necessary footstep into building a foreign relations index like I've always wanted to, but now that I've come to the long awaited stage of actually making a foreign relations table, and spam-tagging all my acquaintances, I've hit a large wall.
I like to base my factbooks (mostly) out of actual Wikipedia factbooks, and I was astonished to find out that most real life nations don't actually rank their best buddies and worst enemies on a numerical scale. Shocking.
TL;DR What are some suggestions the NS community has for a foreign relations index? Should I rank other nations on a scale of 1 to 5 or something else? Penny for your thoughts.
