Osama bin Laden created a global jihadi financial network by leveraging his personal wealth and donors from Muslim organizations. He decentralized al-Qaeda's funding sources to diversify revenue and protect the organization if any single source was disrupted. Al-Qaeda used both legitimate businesses and illicit activities like money laundering through alternative banking systems to self-fund its operations. Bin Laden's financial model inspired other terrorist groups and his ideology ensured al-Qaeda's mission would continue for generations through ongoing global insurgencies. Efforts to counter terrorist financing have increased international cooperation but challenges remain due to the evolving and adaptive nature of such networks.
