...and destroying or damaging >2/3rds of all structures in Gaza and killing tens of thousands of civilians with airstrikes isn't?
Obviously yes, Hamas and Hezbollah indiscriminately firing rockets at Israel consistute war crimes. I assume you must agree that Israel's systematic targeting of schools, hospitals, mosques, and refugee camps would also qualify?
Destroying buildings due to being booby trapped by Hamas; booby trapping I seem to recall was mentioned earlier in this thread as a war crime.
