Role of Intel during World War II

Before World War II the United States was said to the world's only great power without an intelligence organization. There were agencies that collected intelligence, but there was no agency that had any overall authority. The British at the time were extremely successful; they had the abilities to crack even the highest German encryptions. The Brits then urged the United States to generate a centralized intelligence organization; shortly after President Roosevelt established the Office of Strategic Services (OSS).

With these efforts implemented it increased production, collection, and exploitation of important intelligence.
