I think the ‘gift’ was a not so subtle hint that he isn’t going to wait for Obama’s approval before going after Iran’s nuke sites.
I think you are 100% right,
I believe this gift was Netanyahu informing Obama that the Shyt is about to hit the fan.
Not so subtle, indeed. Bibi could have just referenced the scroll in conversation. But to actually hand the President a copy and then to inform the press about it is quite telling. The PM does not trust that the President is intelligent enough to grasp the reality of what lies ahead and the seriousness of Israel’s vow to save and protect themselves. And Netanyahu certainly doesn’t trust the President when it comes to relating the facts of their meeting to the press.
