The document discusses how the atomic bombings of Hiroshima and Nagasaki marked a turning point where total war was no longer tolerated by Western societies due to the immense destructive power of nuclear weapons. This led to the emergence of narrative warfare, where public opinion and media coverage can influence the outcome of conflicts more than military force. Guerrilla groups recognized they did not need to match an enemy's military strength and instead used propaganda and media to undermine public support for wars. The proliferation of nuclear weapons, rise of the UN and human rights, end of colonialism, and growth of global populations have all contributed to narratives becoming more important in warfare.
