In his inaugural address, Kennedy made a comparison of the world now and the world as it was during the American Revolution. He makes it very clear that the difference between these two time periods is that today people have all the power to end poverty and destroy human life. The part of the text where he says this very clearly is:
"Today we celebrate not the victory of a party, but the celebration of freedom - symbolizing an end as well as a beginning - meaning renewal as well as change. The world is very different now. Man has in his mortal hands the power to abolish all forms of human poverty and all forms of abolishing human life. "
