Well, Obama wants to know if Israel's actions were legal or not.... This is to establish if Israel will be charged in a court of law. That's it. Now, what you call "an independent investigation", this was already done and declared by the UN, immediately after the conflict. You remember that, don't you? So, we will have that and Obama's. As far as what will be believed, what will that matter? Take Israel to court if you wish. You get it? This will no longer be a matter for the anti-Semites to judge, like the Goldstone sham, but for a court to do it .....and In this case, there is a lot of information available, thank God.
