The Base is an ideologically motivated violent extremist group founded in 2018. The group has been primarily active in the U.S. and promotes a nihilistic and accelerationist rhetoric— an ideology embraced by white supremacists who have determined that a societal collapse is both imminent and necessary. They advocate for violent actions to create chaos, incite a race war, and establish a white ethno-state. The Base has distributed manuals for lone-wolf terror attacks, bomb making, counter-surveillance, and guerilla warfare to its members. The group also organized training camps in weaponry and military tactics around North America. The network specifically seeks to recruit individuals with military experience so that they can leverage their training. In March 2025, The Base called for targeted assassinations and attacks on critical infrastructure in Ukraine. On Telegram, the group offered cash for volunteer recruits to carry out attacks on critical infrastructure, military and police personnel and vehicles, government buildings, and Ukrainian politicians, particularly in the capital Kyiv and other cities.
