how did war change the way we thing about it?

War has significantly changed the way we think about it over time. Here are the steps to understand how:

1. Historical Perspective: In ancient times, war was often glorified and seen as a noble endeavor, a way for men to prove their courage and for nations to expand their territories. This perspective was largely due to the fact that the full horrors of war were not widely known or understood.

2. Technological Advancements: With the advent of more advanced weaponry and technology, the scale and destructiveness of war increased dramatically. This began to change perceptions, as the potential for mass destruction became more apparent.

3. Media Influence: The advent of mass media and later, the internet, has brought the realities of war into people's homes. Images and stories from the front lines have made the horrors of war more immediate and real, leading to a greater public understanding of its true cost.

4. Psychological Understanding: Advances in psychology have also changed our understanding of war. We now have a better understanding of the psychological impact of war on soldiers and civilians, including post-traumatic stress disorder and other mental health issues.

5. Globalization and Interconnectedness: In today's interconnected world, wars can have far-reaching impacts that go beyond the immediate conflict zone. This has led to a greater awareness of the global implications of war, and a greater emphasis on diplomacy and conflict resolution.

In conclusion, war has changed from being seen as a noble endeavor to being understood as a destructive and traumatic event with far-reaching implications. This shift in perception has been driven by technological advancements, media influence, psychological understanding, and globalization.
