Answer:
Bush's statement captures the essence of nationalism.
Step-by-step explanation:
Nationalism is an ideology based on a person's identification with his own country/nation, supporting that country's interests. The side effect of such an identification is that nationalists value their countries over other nations, groups, ideologies, and cultures. Nationalists tend to regard others as the enemy, as if their country needs their constant work and protection lest it will be attacked or surpassed by others.
President Bush's statement divides people and nations into two categories: allies and enemies. That is typical nationalist thought resulting from fear and terror. In order to defend oneself and one's country, people are capable of viewing the rest of the world as a threat.
