They still haven't clearly said what their game plan was. Get rid of hamas? Or just kill everyone in the process? Cause man idf has alot of collateral damage
it's an Urban warfare, its prone to have collateral damage especially buildings that a terrorist hide and use a basement for tunnels and conceal their maneuver , it'll be bloody for both side but good thing they evacuated civilian since 2-3 weeks ago (and Hamas has 2-3 weeks to prepare defensive operation too)
if you look at the main axis of attack it will be along the coast of Gaza because it's lees populate and less buildings, open terrain for IDF so they can take advantage of fire superiority and avoid collateral damages.
