Anyone else have any success or experience AI player warlike tendancies?
This may be well known to the more experienced, players, but ... 
I was trying to play a peaceful game, with a "tiered" approach to allies (one partnership, one military alliance, etc.).  I was refusing treaty "upgrades".
Then, all of a sudden, after a long stretch of peace, where relations were all very warm and brotherly, within two turns all of them declared war on me.   

  I believe that this may have been precipitated when my score became greater than 500, does this sound correct?
So, no warlike tendencies, just a strong, unified reaction to the perceived strength of my empire.  FWIW, my counter-intel did stop an attempt earlier by one empire that I had no treaty with.
