Steel? Rubber? I don't know. You don't have rubber trees in Birmingham, England, so you need to go get that rubber. But the problem is, everybody wants the rubber, so you have kind of this natural competition that has developed out of industrialization, causing countries to be hungry, to seek raw materials, new markets to sell things, as well as bases, like military bases, so they can go back and be strong militarily. Maine, militarism. The last word is nationalism.
