It's arguable whether that's really trade then - it's a bit more like a mugging.
Well, historically large scale trade has been more like mugging. Perfect "free trade" only exists in dogma/ideology. Just consider the "East India Company", how the rich cities of the american South worked, etc. Also of so-called Banana Republics, Africa colonialism and post-colonialism, etc. (Not to miss the party, USSR also had a whole array of "socialist" countries to buy their production and "trade"). Of course, there are millions of examples of political pressure to "buy our stuff", "give our companies your resources at our terms", etc. A multinational is seldom cosmopolitan -- they go where the might is.
I'm reading it at the moment and, to be honest, I'm finding it utterly fascinating but also a bit depressing. If even half of what that book says is true then I really was very naive about how utterly corrupt the world is at a large scale.
Resources (either shortages or riches) do cause wars, but simple trade links are a great way to prevent wars.
