The world would have changed

[Hmmmm]

I've always wondered how the world would of looked had the Native Americans not been killed to close to extinction, with America currently being at centre stage of every nations affair and wars. If travellers had not set foot on America the Atlantic slave trade to America would of not happened, Somalia despite its tribal wars would of prospered into great things, the middle East would not be a war zone. The world would have been different drastically, perhaps China or Russia would of taken the mantle of current America nothing would of changed.
