The Obama administration has tightened up the process for providing arms to Israel:
White House and State Department officials who were leading U.S. efforts to rein in Israel's military campaign in the Gaza Strip were caught off guard last month when they learned that the Israeli military had been quietly securing supplies of ammunition from the Pentagon without their approval.
Since then the Obama administration has tightened its control on arms transfers to Israel. But Israeli and U.S. officials say that the adroit bureaucratic maneuvering made it plain how little influence the White House and State Department have with the government of Israeli Prime Minister Benjamin Netanyahu —and that both sides know it.
....U.S. officials said Mr. Obama had a particularly combative phone call on Wednesday with Mr. Netanyahu, who they say has pushed the administration aside but wants it to provide Israel with security assurances in exchange for signing onto a long-term deal.
....While Israeli officials have privately told their U.S. counterparts the poor state of relations isn't in Israel's interest long term, they also said they believed Mr. Netanyahu wasn't too worried about the tensions. The reason is that he can rely on the firmness of Israeli support in Congress, even if he doesn't have the White House's full approval for his policies. The prime minister thinks he can simply wait out the current administration, they say.
Well, I'd say the prime minister is probably right. It's not as if Obama has actually done much of substance to put pressure on Israel despite endless provocations from Netanyahu, but it's a very good bet that the next president will do even less. On the Democratic side, Hillary Clinton is the heavy favorite, and she's made it crystal clear that her support for Netanyahu is complete and total. On the Republican side, it doesn't really matter who the nominee is. As long as it's not Rand Paul, Netanyahu can expect unquestioning fealty.
And in the meantime, he can count on the US Congress not really caring that he publicly treats the US president like an errant child. I keep wondering if one day he'll go too far even for Congress, but I've mostly given up. As near as I can tell, there's almost literally nothing he could do that would cause so much as a grumble.
