Not really. Obama will do nothing as usual. he might spout off a few words from the golf course, but two US allies won't get anything more than that.
So, yes, it will play into his diplomatic strengths...
My money's on the US standing aside and hand-wringing, perhaps with some pretense of trying to get both of them to walk it back a bit. Since we have a lot more leverage with Israel due to giving them a lot more aid annually, I expect Israel will receive the most pressure from Kerry and his minions, despite being far and away the most-injured party.
