Final answer:
According to Paine, war is caused by the desire to protect or gain territory and wealth, and the need to preserve liberty and autonomy.
Step-by-step explanation:
According to Paine, the main cause of war is the desire to protect or gain territory and wealth, as well as the need to preserve liberty and autonomy. This can be seen throughout human history, from Vikings attacking for loot to Europeans exploring to claim resources. Paine argues that nearly all conflicts are spurred by these basic desires. economic disparities and competition, political ideologies and power struggles, religious differences and cultural clashes, and social injustice and inequality can all contribute to these desires and therefore be factors that cause war.
