Terrorism is defined in various ways around the globe, with policymakers distinguishing between threats that arise from within a nation (domestic terrorism) and those that come from outside its borders (international terrorism). A common thread in these definitions is the underlying political or ideological motivation for violent acts.
In the United States, the Federal Bureau of Investigation (FBI) characterizes international terrorism as "violent, criminal acts carried out by individuals or groups to promote ideological goals influenced by domestic factors, including political, religious, social, racial, or environmental issues."
Historically, terrorists worldwide have pursued a range of political objectives. While discussions about terrorist threats in the U.S. have intensified, particularly since the September 11 attacks, it's noteworthy that the majority of terrorism incidents occur outside the U.S. Most recent attacks have taken place in countries like Afghanistan, Burkina Faso, Mali, Pakistan, and Somalia. In addition, while international terrorism remains a significant concern for U.S. security officials, there has been a marked increase in the focus on domestic terrorism as a pressing national security issue in recent years.
