>Why would blackwater violate a contract with a paying customer?
Because their other paying customers, who pay them much more than you do, will compell them to?
>Power is not zero-sum. Trade is positive sum. That is very, very basic economics.
Power is zero-sum when we think of it as a percentage of "total power". It's irrational to think of wealth that way, because people care more about what a dollar can do for them than what percentage of world's wealth that dollar represents. With power, there is no such distinction. What your power can do for you is directly proportional to what percentage of "total power" you have. If there is a new actor and his power increases, everyone else's power (averaged out) decreases proportionally.
