...when Caesar is due north, and Alexander is due east, and you are the population/land/GNP king who doesn't start wars but refuses all demands. Caesar invades, you takes three cities, destroy his SOD, and win a cease fire (by PAYING him

). Seven turns into the peace treaty, Alexander invades, you take two of HIS cities, destroy SOD, etc., and manage to wrangle a couple bucks from him in the exchange. Caesar invades again, stalemate ensues, Alexander invades again, peace with Caesar.
Repeat this cycle SEVEN more times, my empire is unit-less, down four cities, with more WW than should be possible, tech loser, etc., etc.
Every time I was close to decapitating an opponent, the other would declare war.
All other civ's were hopelessly tiny, though advanced, and wouldn't join in anyway. Didn't help that all I could offer at the end was 1-2 gps...
