 there probably wouldn't be any American history, at least not in the way we know it. And think about the impact the United States has had in the world. Think about its role in the two world wars and the Cold War. Think about its role as the leader of the free world. Think about its technological achievements, the birth of flight, the landing on the moon, the creation of the internet. Think of its cultural significance. And think of its economic dominance. Do these things still happen in the same way and at the same time? Maybe. Who really knows?
