Final answer:
President Clinton's mention of a "line" reflects the shift from a Cold War mentality toward a new foreign policy framework where the U.S. addresses international issues individually, without the influence of superpower rivalry.
Step-by-step explanation:
When President Clinton speaks of a "line" that divides the world, he is referring to the ideological and strategic divisions that shaped international relations during the Cold War era.
These divisions compelled the United States to view various global conflicts and political upheavals through the prism of its rivalry with the Soviet Union.
With the dissolution of the Soviet Union, President Clinton recognized that a new paradigm was necessary—one where the United States could address international crises, such as those in the Middle East, the Balkans, and Africa, on their own terms rather than as part of a struggle against a singular adversary.
This adjustment in foreign policy approach allowed for more nuanced engagement with global issues and emphasized the use of the United States' military superiority and international influence as tools to maintain peace.
