Since the end of the nineteenth century, it had been clear that the resource-rich and rapidly industrializing United States was the world's rising superpower, but the US was reluctant to adopt this mantle. This was rooted in history: the country took to heart George Washington's advice in his Farewell Address that it steer clear of involvement in European politics and conflicts.
The US did enter belatedly into World War I, but after that war, it retreated back into isolationism, stunningly refusing to enter the League of Nations, despite this organization being close to the heart of President Woodrow Wilson.

It affected people from all over the world, from all races, from all backgrounds and social hierarchies. Tens of millions of people have died from it, and every day there are tens of thousands newly infected, mostly in the less developed countries, having their lives doomed even before they start as most of them get it from their parents when they have been conceived.
