During the era of "Old Terrorism", which behavior characterized international actions?

The behavior during the era of "Old Terrorism" is characterized by the dynamics of the Cold War and the ideological motivations of various revolutionary movements. The period saw intense rivalry between superpowers, specifically the United States and the Soviet Union, which often played out in the context of international terrorism. This rivalry influenced the actions of several revolutionary groups, many of whom were inspired by Marxist ideology and sought to challenge established powers.

Additionally, the blend of nationalism and Marxism among revolutionaries is a significant characteristic of this era. Various groups were not just fighting for power; they were also attempting to liberate themselves from colonial rule or oppressive regimes using terrorist tactics as a means of achieving their goals. As these ideologies intersected, movements often adopted terroristic methods to draw attention to their causes and to instigate change, making this combination particularly relevant to international actions during that time.

Thus, the selection of both the Cold War rivalry and the blend of nationalism and Marxism accurately captures the complexity of international behavior in the context of "Old Terrorism." It reflects how geopolitical tensions and revolutionary ideologies interplayed in shaping the actions of states and non-state actors involved in terrorism during that era.
