John Kerry (but not the petty, Netanyahu-loathing POTUS) called Bibi to give him official U.S. guv'mint congrats on his election victory. (I'm sure Kerry managed to sound tres sincere.)
Don't get the wrong (i.e. the right) idea here, though. Apparently, Obama is planning to call. Some time. Eventually. No one knows when.
Update: Of course, the sourest grapes of all can be found in deranged, Zion-loathing lefty Israeli rag, Ha'aretz.
Update: Some of the world leaders Obama has called to congratulate post-"election": Putin, Iran's Rouhani and China's top Communist.
