[dropcap]I[/dropcap]n a “Means of First Resort: Explaining ‘Hot Pursuit’ in International Relations,” Lionel Beehner explores variation in the practice of “Hot Pursuit” by different countries. The author defines Hot pursuit as “a limited violation of sovereignty by a state…using military forces in pursuit of violent…non-state actors” (3). Hot pursuit can entail a number of different tactics—from commando raids, to border incursions, to air strikes, and can vary in intensity. However, in Beehner’s definition, hot pursuit “must involve the physical transgression of an international territorial border” (4). In framing the article, Beehner argues that there is little work on this subject and that this is likely due to hot pursuit inhabiting a “hard-to-define gray zone between interstate and intrastate wars” and rarely garners media coverage due to low casualties or its covert nature (2). Beehner’s main focus is not on whether hot pursuit occurs but in variation in attitudes and practices of hot pursuit across states and time.
