It´s false.
The inaugural ceremony is a defining moment in a president´s career and John F. Kennedy knew this as he prepared for his own inaugural on January 20th of 1961. He wanted his addres to be short and clear; devoid of any partisan rethoric and focused on foreign policy.
Inmediatly after reciting the oath of office, the President turned to adrresed the crowd gathered at the Capitol. His was the first delivered to a televised audience in color and it´s considered one of the best presidential inaugural speeches in American history.
He began constructing the speech in November of 1960 with friends and advisers who submitted ideas but himself prepared the whole speech. Every sentence was worked, reworked and reduced according to his helpers. It was a piece of oratory that a generational change in the White House and called on the nation to combat " Tyranny, poverty, disease and war itslef."
I will copy a quotation of the most famous part of the speech that summon it up some of the ideas expressed above:
"Let the word go forth from this time and place, to friend and foe alike, that the torch has been passed to a new generation of Americans—born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage—and unwilling to witness or permit the slow undoing of those human rights to which this nation has always been committed, and to which we are committed today at home and around the world.
And so, my fellow Americans: ask not what your country can do for you—ask what you can do for your country."
He assumed as president at the height of the Cold War and he highlighted the newly discovered dangers of nuclear power and the accelerating arms race. One of the main ideas of the speech was that the countries focus on pure firepowershould be replaced with a focus on maintenance of international relations and helping the impoverished in the world.
What we can deduce from the information given above is that JFK did the opposite of what the proposition tells so this is why it is a FALSE proposition.
Hope this help you. Regards.
