Prime Minister Benjamin Netanyahu, presently in a tough relationship with US President Barack Obama, distanced himself Saturday night from a critical advertisement to run this weekend in the US against Obama’s possible successor, Hillary Clinton.A senior official in the Prime Minister’s Office said it knew nothing about the ad, paid for by the right-wing Emergency Committee for Israel, a group The New York Times describes as “strongly” for Netanyahu.The Emergency Committee for Israel was founded by William Kristol, editor of The Weekly Standard, and has funded campaigns against candidates it has deemed bad for Israel.The advertisement, with ominous music, has a narrator saying Obama is holding secret talks with Iran even as it threatens to wipe Israel off the map.“The Israeli prime minister is coming to Washington, but Obama won’t talk to him,” the narrator says. “Instead, Obama and anti-Israel Democrats are boycotting him. Israel’s friends, Democrats and Republicans, are fighting back. But where is Hillary Clinton? Does she support the boycotters, or is she too afraid to stand up to them?” The senior PMO official said the ad “only reinforces a perception of partisanship that the prime minister strongly believes should never be injected into the US-Israel relationship.”According to the Times, the ad will run on various networks from Sunday to Tuesday. Netanyahu is scheduled to speak to Congress on Tuesday morning.
