Answer:
by claiming that the responsibility to defend freedom has been passed to a new generation
Explanation:
The fourth paragraph of the speech given below says:
"Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty.
This much we pledge--and more."
Hence, he connects the present to the past by claiming that the responsibility to defend freedom has been passed to a new generation.
