So far, Israel is losing more troops than they did in the last ground war:
Israel's casualties also mounted, with the military announcing the deaths of two more soldiers, bringing the number of army fatalities to 27 - almost three times as many as were killed in the last ground invasion of Gaza, in a 2008-2009 war.
Israel lost 10 in that battlefield victory over Hamas.
So I have to assume that Hamas learned more from that defeat than Israel did.
It all depends on what Israel's objective is before we find out if Israel actually learned more. Will Israel achieve more to justify the higher casualties?
