Many military experts the world over disagree with Goldstone's assertions claiming Israel committed war crimes (indeed, if we accept Goldstone's definition, it means that almost every general who led troops in any major conflict of the 20th century is also a "war criminal" rendering the concept meaningless). That said, everyone agrees that the unrestricted use of artillery on civilians IS a war crime. Instead of treating Palestinians like children and obfuscating, the world should continue to assert this basic principle.
