This is inevitable. An army cannot be fully transparent during a war without compromising the security of its troops and citizens.
But we do have history.
The most famous - and most famously flawed - indictment of Israeli actions during Operation Cast Lead in 2009 came from the UN's Goldstone Report.
What most people did not hear about were the two responses made by the IDF to the report.
When you read the responses, you get the impression that Goldstone, Human Rights Watch, Amnesty and the media's criticisms of the IDF are somewhat like an 8-year old trying to understand the US tax code. Their assumptions and guesses about how a military works, what the intent of the IDF was in various operations, and even about what international law really says are breathtakingly naive.
So far, the level of criticism indicates that no one has bothered to do the most basic research, reflecting a willful blindness rather than an honest desire to gather facts.
There could be valid criticisms of IDF actions in the previous Gaza ground war. But the critics - if they are going to be intellectually honest - owe it to themselves to actually read the IDF responses to criticisms last time, if for no other reason than to not be as staggeringly ignorant this time around.
