When might military support be necessary for governance in a state?

Military support may be necessary for governance in a state primarily when the government can no longer perform basic civil functions. In situations where a state's governance has broken down due to internal conflict, natural disasters, political instability, or other crises, essential services such as law enforcement, emergency response, and public order may become ineffective or nonexistent. In these scenarios, the military can step in to provide stability, restore order, ensure safety for citizens, and facilitate the delivery of critical services until a functional government can be reestablished.

This role often involves not only securing infrastructure and maintaining order but also aiding in humanitarian efforts and rebuilding governance systems. The military's involvement in governance under these circumstances can be pivotal in preventing a complete collapse and in laying the groundwork for future democratic processes.

The other scenarios described do not typically necessitate military involvement in governance. For instance, an abundance of resources may strengthen a government’s capacity but does not inherently require military support. Similarly, while attempting to overthrow a regime might involve military action, it generally does not pertain to governance in the sense of stabilization and support of existing structures. Finally, preparing for international negotiations is a diplomatic activity that usually falls outside the military's purview unless specific security concerns arise during those discussions.
