I do not see any real reason to rush into Gaza. Hamas is contained. A hasty ground invasion will just cause more death and destruction of children. Leading to more negative press/protests against Israel throughout the world.
Surgical strikes and special forces could eliminate most of the issues.
Gaza is just a side show.
The Iranian strategy is to destroy the IDF with Hezbollah with invasion from Syria and Lebanon.
How do you surgically strike tunnels buried deep, with entries in hospitals, and who knows where?
