I say heavily because they have mentioned various success their covert units have had, one example is them sneaking into a tunnel while everyone was busy firing rockets at Israel then taking all the secret documents revealing the location of other tunnel networks and fighters.

Of course Israel wants to find the kidnapped people and free them, of course they want to kill or capture the Hamas leaders, and of course they don't want to kill innocent people. Those aren't easy things in the situation they're in.

The leader of Hamas assuming he's back from his recent trip to Iran is at home in Doha, the local commanders are in their bases deep under hospitals, the fighters are dressed as civilians and of course get added to the civilian casualties lists - especially the teenagers fighting for Hamas...

People act like Israel is in an easy position but that really isn't close to reality.
