What violence and destruction that occurred during world war 2 led to?

Answer 1

World War II resulted in unprecedented violence and destruction, including the Holocaust, where six million Jews and millions of others were systematically murdered. Widespread bombings of cities, such as the Blitz in London and the firebombing of Dresden and Tokyo, caused massive civilian casualties and infrastructure devastation. The use of atomic bombs on Hiroshima and Nagasaki not only led to immediate loss of life but also long-term health effects and environmental destruction. These events ultimately reshaped global politics, leading to the establishment of the United Nations and a renewed focus on human rights and international cooperation to prevent future atrocities.
