What action is described as expressing intent to support terrorism through violence?

The action that embodies expressing intent to support terrorism through violence is indeed engaging in violence. This choice directly aligns with the notion of taking concrete, aggressive steps that manifest an intent to harm, either by inflicting physical damage or by threatening safety. Violence, in this context, reflects actual participation or instigation of acts that can harm individuals or groups, leading to criminal actions associated with terrorism.

Recruitment for terrorism, while related to the support of terrorist activities, refers more to the process of persuading others to commit acts of terrorism rather than directly expressing intent through violence. Collecting intelligence involves gathering information that may or may not lead to violent outcomes, and browsing terrorist websites typically denotes passive engagement, rather than an active expression of intent to cause harm. Therefore, engaging in violence is the most definitive action that indicates a direct commitment to supporting terrorism.
