How can a civil war in a neighboring country encourage rebellion?

A civil war in a neighboring country can significantly encourage rebellion by altering the political and security landscape of nearby states. This influence typically manifests through several key mechanisms:

• Mobilization and Emulation: The presence of conflict nearby can facilitate violent mobilization by providing successful models of rebellion. Groups may be inspired to emulate these movements, gaining moral incentives and motivation from the perceived success of others in similar political or economic conditions.12
• Transnational Support: Because ethnic groups often span international borders, transnational kin frequently provide essential resources, including arms, combatants, and financial or political support, to insurgencies in neighboring states.12
• Spillover and Contagion: Conflicts can spread across borders through "contagion," where the involvement of kinfolk in a neighboring country draws in foreign fighters. Additionally, the porous nature of international borders makes it difficult for governments to contain insurgencies that utilize neighboring territory as a base of operations.12
• Strategic Exploitation: Neighboring states or regional powers may intentionally support insurgencies in rival countries to gain military, economic, or political advantages, further inflaming local tensions.12
