An Inaugural Address - But who's?

This is an excerpt from a recent (post WWII) President's innaugural address:

" 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, in order to assure the survival and the success of liberty.

This much we pledge - and more.

To those old allies whose cultural and spiritual origins we share, we pledge the loyalty of faithful friends. United, there is little we cannot do in a host of cooperative ventures. Divided, there is little we can do - for we dare not meet a powerful challenge at odds and split asunder.

To those new States whom we welcome to the ranks of the free, we pledge our word that one form of colonial control shall not have passed away merely to be replaced by a far more iron tyranny. We shall not always expect to find them supporting our view. But we shall always hope to find them strongly supporting their own freedom -and to remember that, in the past, those who foolishly sought power by riding the back of the tiger ended up inside."

But who's?
