What is a key aspect of lone actor terrorism?

Lone actor terrorism is characterized by attacks that are carried out by individuals acting independently, without direct support or coordination from organized groups. This type of terrorism relies on the motivations and ideologies of the individual, who may be inspired by extremist beliefs but operates without formal affiliations. The significance of this aspect lies in the unpredictability and challenges that law enforcement faces, as these individuals often evade detection and can act without warning. The other options describe elements that do not align with the essence of lone actor terrorism, such as the involvement of multiple groups, external international support, or a restriction to foreign locations, which are not inherent to the definition of this phenomenon.
