Iran is facing a pivotal crisis as nationwide protests, fueled by economic collapse and government corruption, directly challenge the Islamic Republic's authority. Security forces have responded with deadly force and internet blackouts, but the unrest continues to grow, exposing deep fractures within the regime. The future of Iran now hinges on the loyalty and actions of the Revolutionary Guard and its Basij paramilitary force, which are essential to maintaining internal control. If these forces remain united behind the clerical leadership, the regime may survive through repression; if they splinter or hesitate, Iran could see transformative change. Ultimately, the outcome depends less on foreign intervention and more on critical decisions made within Iran's own power structures.
