Why is stopping ISIS so difficult?

Stopping ISIS is difficult due to several factors, including its decentralized structure and ability to adapt quickly to military pressures. The group exploits regional instability, sectarian divisions, and local grievances to recruit and maintain support. Furthermore, ISIS has established a global network, enabling it to inspire and coordinate attacks beyond its territorial strongholds. Efforts to combat ISIS are further complicated by the complex political landscapes and conflicts in the Middle East.
