Reza Pahlavi, the exiled son of Iran's last shah, has publicly positioned his potential return as conditional on the Islamic Republic's collapse, stating in a July 2026 Reuters interview that the regime is at its weakest point in 47 years and that regime change appears close. He has accepted a transitional leadership role to oversee a shift to secular democracy via a constitutional assembly, while emphasizing preparation to enter Iran alongside any popular uprising or post-regime transition. Key drivers include ongoing diaspora and domestic opposition coordination, statements rejecting negotiations with the current authorities, and assessments of internal repression and external pressures, though no verified entry has occurred and structural barriers such as regime control persist.
