Who is considered to be a Homegrown Violent Extremist?

The concept of a Homegrown Violent Extremist (HVE) refers specifically to individuals who are radicalized within their home country and decide to engage in violence or terrorism, often motivated by ideologies that are aligned with foreign extremist groups. While the answer provided identifies a U.S. individual engaging in terrorism for foreign organizations, which may capture a relevant aspect of HVE behavior, it doesn't fully encompass the definition of "homegrown."

A true Homegrown Violent Extremist often does not need to be acting in direct coordination with a foreign entity but is instead motivated by the ideologies of such groups and decides to act within their own country. This person can become radicalized through various means, including online propaganda or local networks.

The other choices do not quite fit the definition of a Homegrown Violent Extremist. The advocacy for social justice does not necessarily involve violent extremism; foreign nationals are not classified as homegrown, and acting within legal boundaries would negate the violent aspect necessary to classify someone under this term.

Therefore, a Homegrown Violent Extremist is best characterized by their radicalization within their own societal context, which often leads them to carry out acts of violence inspired by extremist ideologies.
