What is included in the category of international terrorism?

International terrorism encompasses violent acts that transcend national borders and may involve individuals or groups that are influenced by ideologies from other countries. This includes homegrown violent extremists who may be motivated by radical beliefs or ideologies originating abroad. Such individuals can carry out attacks within their own country, yet their motivations are rooted in foreign influences or beliefs, thereby categorizing these actions as international terrorism.

This understanding highlights the complex nature of terrorism today, where local individuals can inspire international connections through shared ideologies, even if they are acting within their own country. This reflects the evolving dynamics of terrorism, where traditional borders no longer fully define the motivations or affiliations that can spur violent acts.

In contrast, the other options do not fully capture the essence of what is classified as international terrorism. Specifically, violent acts by state actors tend to fall under different classifications of conflict, while attacks planned solely outside the U.S. disregard the global implications of ideologies that inspire domestic acts. Lastly, terrorism as a response to military actions may not necessarily reflect the international nature of motivations aligned with global ideologies.
