Terrorist group survival as a measure of effectiveness

Some terrorist groups only carry out one attack and then disappear, while others wage campaigns of terror for decades. Why do some terrorist groups last much longer than others? A growing body of research provides in-depth empirical evaluation of this important question (Cronin 2006, 2009; Daxecker and Hess 2013; Gaibulloev and Sandler 2014). However, there has been little effort to consolidate the findings that exist thus far.
