Terrorism (Conspiracy) 

Terrorism in the modern sense is violence or other harmful acts committed (or threatened) against civilians for political or other ideological goals. Most definitions of terrorism include only those acts which are intended to create fear or "terror", are perpetrated for an ideological goal (as opposed to a lone attack), and deliberately target or disregard the safety of non-combatants. Many definitions also include only acts of unlawful violence.

As a form of unconventional warfare, terrorism is sometimes used when attempting to force political change by convincing a government or population to agree to demands to avoid future harm or fear of harm, destabilizing an existing government, motivating a disgruntled population to join an uprising, escalating a conflict in the hopes of disrupting the status quo, expressing a grievance, or drawing attention to a cause.

Terrorism has been used by a broad array of political organizations in furthering their objectives; both right-wing and left-wing political parties, nationalistic, and religious groups, revolutionaries and ruling governments. The presence of non-state actors in widespread armed conflict has created controversy regarding the application of the laws of war.
