What term refers to individuals radicalized without influence from foreign interests?

The term that accurately describes individuals who are radicalized without influence from foreign interests is "Domestic Extremists." Domestic extremism typically involves individuals or groups that engage in violent or unlawful actions based on ideologies that are rooted within their own country. These individuals often become radicalized through domestic social movements, local grievances, or cultural factors instead of being influenced by outside terrorist organizations.

In contrast, radical ideologues typically refer more broadly to individuals who hold extreme views, but this term does not specifically identify the domestic connection to their radicalization. Insurgents may operate within a country and could potentially be domestic, but they often seek to overthrow a government or challenge a political system, which may not align with the concept of radicalization without foreign influence. International terrorists, on the other hand, are explicitly connected to global jihadist movements or foreign terrorist organizations, thus remaining distinctly separate from the idea of domestic radicalization.
