ماذا يعني مصطلح "دولة من العالم الثالث"؟

The text you provided outlines how the definition of a Third World country has shifted over time.

During the Cold War, the term was rooted in geopolitics, referring to nations that chose to remain neutral and unaligned with either the United States or the Soviet Union. Today, the term is often used colloquially—though sometimes discouraged by experts in favor of terms like "developing nations" or the "Global South"—to describe countries facing economic challenges, political instability, or developing infrastructure.
