How do these two accounts reflect certain points of view? Which source is more reliable and why? Explain your answer, supporting it with reasons and evidence from the documents.

Document 1: The United States had one goal following the war—to expand its military and economic power across Asia. On June 25, 1950, President Truman ordered the invasion of North Korea. The United States manipulated the United Nations to build an army that included fifteen nations. This American army marched across the 38th parallel and spread across the peninsula, bringing war to the banks of the Yula River. To resist the Americans and defend China, the People's Volunteer Army joined the North Korean army in repelling the American invasion.

Document 2: After the division, North Korea attempted to overthrow South Korea's government. When this proved impossible, the North Korean communists began to prepare themselves for war while pretending to negotiate peacefully. On June 25, 1950, the north began its invasion of the south. The south was taken by surprise, but the armies of South Korea fought bravely to defend their liberties. This action moved the United Nations Security Council to declare the invasion by the north illegal and a threat to peace. A decision was made to help the south, and a UN army, led by the United States, Britain, and France, joined the South Korean forces in an effort to repel the invasion.
