Israel needs no 'green light' from the US for an internal probe. Nor does it need a 'red light' to do the right thing. If Israel has nothing to fear, then ANY probe will do. But we all understand that mistakes were made. And thus Netanyahu is eager to use the USA as an excuse to prevent any open investigation. There are degrees and types of 'courage'. There is the terrible reality that at some point, in some way all are cowards. There is also a truth that most are capable of heroics given the right circumstance. The rash physical 'courage' of youth is no measure for the thoughtful courage of age. Now Netanyahu and Barak want the USA to save them by it's actions from their actions. Cowards.
