That this 'deal' dates back to July 2008, long before Barak Obama was elected, much less president the reality is that this story is nothing but 'spin.' The 'message' we are to learn is that there is no trouble, no problem, that everything is absolutely fine between Israel and the USA. Amos Harel is not Ze'ev Schiff. He pimps the story he is given.
