John Kennedy actually said...

"I think you will find as you go around the United States that there is no country or people for whom my countrymen have a stronger feeling of admiration for than the people of Poland."

"I hope when you go back home that you will have some pleasant memories of the United States and will say on occasions a few kind words in our behalf."

"In addition, I hope you will examine our political structure, which is not perhaps the most efficient in the world."

"We are glad that you are here to take a long look at us."
