Step-by-step explanation:
The statement is false.
The United States rejected the League of Nations because of its policies of isolationism, not internationalism.
Isolationism is a foreign policy approach that aims to keep a nation separate from international affairs. The United States sought to avoid getting entangled in foreign conflicts and preferred to focus on domestic issues. This stance was at odds with the League of Nations' mission of promoting international cooperation and collective security.
