Those who believe in the inevitable progress of man, forget that the twentieth century was the bloodiest, most destructive century in human history. The century's two world wars alone resulted in the deaths of at least 60 million people.
The 20th century was marked by an explosive convergence of ideological, technological, economic, geopolitical and sociopolitical forces, creating a highly volatile environment that led to unprecedented violence and devastation, while at the same time delivering the highest standard of living in history. This era demonstrated how technological advancements, in the absence of corresponding developments in legal and moral frameworks, can lead to massive human suffering.
While technology significantly enhanced the destructiveness of warfare during the 20th century, the deeper causes of this violence lay in the prevailing belief systems and moral frameworks. These frameworks, which include religious, philosophical, and cultural codes, are vital as they shape societal norms about what is deemed justifiable or unacceptable behavior, especially concerning the use of violence.
