Richard Goldstone accuses NATO of war crimes - not

Richard Goldstone stated about Israel "is that they've got the munitions and technology such that that doesn't happen in error...... All of those things were done intentionally."
However, when Eight Afghans are killed in a NATO air strike, the Afghan defense ministry reported a base was "mistakenly" hit.
Why are NATO trips allowed to make mistakes without being subject to a Goldstone report while Israel is deemed to commit intentional war crimes?
"At least eight Afghans working with US forces have been killed in a Nato air strike in north-western Afghanistan, the defence ministry in Kabul says.
Nato confirms an air strike was ordered and is investigating whether it was the cause of the deaths on Friday.
....The Afghan defence ministry said a base housing coalition troops and Afghan security forces was mistakenly hit by the air strike.
Four Afghan soldiers, three police and another person believed to have been an interpreter were killed."
