This reminds me a scene of the wonderful AniMatrix clips. Here is what I recalled (may not be exactly accurate): Escaped robots established their own country in remote area and started to export products for natural resources. Since robots never need a salary and can keep producing goods 24/7, human beings cannot compete and all countries ran into deficits and their societies collapsed. In the end, all countries blockaded the Robot country and the war started, then the rest is history.
