Maximum neighbor hypothesis
The Maximum neighbor hypothesis (hipótesis vecinal máxima in Spanish) or neighbor hypothesis 3 (hipótesis vecinal 3; HV3 in Spanish) is a strategic concept used in international analysis and defense in Chile since the late 19th century. It argues that in the event of a conflict with one neighboring country, it is highly likely that the other two border countries will side with the first one against Chile. HV3 has been studied in military and political circles based on historical precedents and the dynamics of international relations in the region.
