Opportunity is a big factor in an AI declaring war or not.
The AI def looks at their military, then looks at your military and if you are deemed weak, they will demand animals, goods or smokes.
Or they park some guys with weapons at your borders and snag up some workers when they pass by.
I always make sure I got enough fighting power, otherwise the AI will just see me as a lame duck that will even wake Ghandi from his peaceful meditations.
