Step-by-step explanation:
The victory of the United States in various conflicts, such as the Revolutionary War, the War of 1812, and World War II, involved numerous critical events. George Washington's victory at Trenton was pivotal in the Revolutionary War, boosting American morale and proving crucial in rallying the colonies. During the War of 1812, despite setbacks such as the burning of Washington D.C., the resilience of U.S. forces at Baltimore and the failure of the British to secure another victory were significant. In World War II, events like D-Day and the technological advances of the Allies contributed to the eventual victory. The role that technology played for the Allies was instrumental across all theaters of war. Assessments of these periods also consider the United States' adherence to the principles laid out in the Atlantic Charter and democratic values.
