Hamas is considered a terrorist organization by most of the western world. Hamas now runs the government in Palestine. Sounds like check mate by the israeli's to me. Palestine fucked up by letting a terrorist organization take over their country.
Also, war crimes as a subject is always brought on by the winners, just like the telling of history.
The world is a brutal place. Hamas has proved they are not a military match for israel and the war will continue until israel has complete control of the region. That's how one sided conflicts have happened historically.
