The IDF estimates that occupying Gaza City and completely cleansing it, above and below ground, will cost the lives of hundreds of warfighters and will take at least a full year to fully pacify the enclave. This estimate was also presented to the cabinet, not as an exact result of a mathematical equation, but to clarify to decision-makers that this will not be just another operation, but rather a heavy and lengthy campaign, and no one can guarantee that it will end with a "decisive" victory for HAMAS.
