 Since the Supreme Leader of Iran is the ultimate clerical authority, Hezbollah's leaders have appealed to him "for guidance and directives in cases when Hezbollah's collective leadership [was] too divided over issues and fail [ed] to reach a consensus." After the death of Iran's first Supreme Leader, Khomeini, Hezbollah's governing bodies developed a more "independent role" and appealed to Iran less often. Since the Second Lebanon War, however, Iran has restructured Hezbollah to limit the power of Hassan Nasrallah, and invested billions of dollars "rehabilitating" Hezbollah.
