What is NOT one of the primary focuses of a terrorist attack?

The primary focus of a terrorist attack often revolves around instilling fear, causing mass casualties, and impacting resources. The goal of terrorism is typically to create panic and disrupt life, which aligns with heightened fear, loss of resources, and mass casualties, as these elements contribute to creating chaos and drawing attention to the terrorists' cause or grievances.

In contrast, securing governmental stability is not a primary focus of a terrorist attack. Terrorist actions are usually aimed at destabilizing governments, not securing them. Terrorists often seek to undermine existing authorities, create division, and provoke responses that can further their objectives. Therefore, the idea of securing governmental stability is not consistent with the goals of most terrorist acts, making it the correct choice as something that is not a primary focus of such attacks.
