Abstract: The article presents a reprint of the article "The Other Forever War" by Jack Goldsmith and Matthew C. Waxman, which appeared in the "Time" magazine. It discusses the comprehensive and sustained counterterrorism strategy launched by the U.S. against the Islamic State terrorist group under the administration of President Barack Obama. The controversial use of the 2001 Authorization to Use Military Force (AUMF) as the legal foundation for war against the Islamic State was noted.
