To achieve your goal, you will need to change the very fundamental fabric of humanity and the reality of resource scarcity. Here are some examples that can lead to war: economic gain,territorial gain, religion, nationalism, revenge, civil strife, defensive. Below are a few expressions of what it can look like:

* Actor A burned your crops -> Do nothing (appeasement)

* Actor B disrupted your servers causing economic losses -> Do nothing (appeasement)

* Actor C stole your technology and sold it to everyone by a fraction of your price -> Do nothing (appeasement)

* Actor D manipulated a group within your nation to cause internal conflict -> Do nothing (appeasement)

* Actor E invaded your land and claimed as their -> Do nothing (appeasement)

* Actor F used their position of power to gain concessions from you -> Do nothing (appeasement)

* Actor G defamed you, leading to society admonishing you and potentially imprisonment -> Do nothing (appeasement)

Each Actor can be seen as both individuals or nations that are in existence today. Every one has their own set of interests and rationale for acting in certain ways.
