In a stunning sign that Iran's regime is fracturing from within, reports have emerged that members of the Islamic Revolutionary Guard Corps have opened fire on fellow IRGC soldiers, exposing a level of internal chaos that analysts say could signal the beginning of the end for the Islamic Republic's grip on power. The IRGC, long considered the backbone of the regime and one of the most feared military organizations in the Middle East, now appears to be turning on itself as deep divisions and escalating infighting boil over into outright violence. This extraordinary development is being watched closely by American and Israeli intelligence officials who have long warned that Tehran's regime is far more fragile than it projects to the outside world.
