Answer: Despite many major developments, the basic principles of the country’s founders are still at play.
In the third paragraph of his inaugural address, JFK discusses the way the world is nowadays, and the way it was back when the United States was born. He argues that the world is very different now, as we now have the tools to eliminate all poverty, but also all life from Earth. However, he believes that the revolutionary ideals of the Founding Fathers are still very relevant in modern times all over the world.
