The surprise attack on Israel by Hamas militants on Oct. 7 raises the specter of unconventional warfare being waged to achieve political objectives in other parts of the world as well, including in Japan’s backyard.
Unconventional warfare is a blanket term used to describe all military and quasi-military operations outside of conventional warfare, namely wars fought between states. It includes, but is not exclusive to, revolutionary wars and their constituents, subversion and guerrilla operations, as well as other types of special operations.
The tactics used by Hamas are clear examples of unconventional warfare. These include the launching of "homemade" rockets, the breaching of Israeli borders using motor gliders, bulldozers and boats, as well as the indiscriminate killing and kidnapping of civilians — including children and the elderly — to use as hostages.
