Answer:
Kennedy said "whether you are a citizen of America or a citizen of the world" to:

To create a commonality between people.
Explanation:
In this sentence, Kennedy was not only talking for "The United States" citizens, but he was also talking to everyone that could listen to him. Because he wanted to establish an equality rule to define his speech. He had the intention to speak for all and to all, not only a sector of the population because he considered that his words were not going to be important only for "The United States" citizens, but for everyone.
