**Intact Gift Giving Condition book**

But what made the United States and the Soviet Union such fierce opponents? The Cold War was one of the longest and most tense rivalries in modern history—a competition between two powerful countries that lasted more than 40 years. This book helps kids explore the big ideas behind the Cold War in a clear and easy-to-understand way. Divided into six main sections, it looks at why the two sides disagreed, how they competed without actually going to war, and what life was like for people living through this extraordinary time.
