Where some on the right would see nothing more than an "illegal immigrant," Obama recognizes a young adult who has been in this country, for example, for twenty out of the twenty-five years of her life and who has gone through an irreversible process of Americanization. That person is nothing but an American in terms of her national identity. He understands what it would mean to that person to be expelled from the only homeland she has essentially ever known. President Obama understands how national identities are formed, both on the individual and the societal level. He understand how and why an American comes to feel an attachment to this country and to his fellow Americans.
