The Second World War was history's largest and most significant armed conflict. It served as the breeding ground for the modern structure of security and intelligence, and for the postwar balance of power that formed the framework for the Cold War.

To a great extent, victory was forged in the work of British and American intelligence services, who ultimately overcame their foes' efforts.

<h3>What is
Cross-sectional research?</h3>
A cross-sectional study is a form of observational study in medical research, social science, and biology that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.
Cross-sectional studies are used to analyze a population's illness burden or health requirements, and they are especially effective in informing health resource planning and allocation. A cross-sectional survey can be used to measure the burden of a certain disease in a defined population.
Cross-sectional studies capture a single point in time, gathering data from a research group at a particular point. This is often done with a single survey, questionnaire, or observation.
