WASHINGTON — For six years, President Barack Obama and Israeli Prime Minister Benjamin Netanyahu have been on a collision course over how to halt Iran’s nuclear ambitions, a high-stakes endeavor both men see as a centerpiece of their legacies.
The coming weeks will put the relationship between their countries, which otherwise remain stalwart allies, to one of its toughest tests.
Netanyahu is bound for Washington for an address to Congress on Tuesday aimed at derailing Obama’s cherished bid for a diplomatic deal with Iran.
At the same time, Secretary of State John Kerry and other international negotiators will be in Switzerland for talks with the Iranians, trying for a framework agreement before a late March deadline.
In between are Israel’s elections March 17, which have heightened the political overtones of Netanyahu’s visit to Washington.
The prime minister is speaking to Congress at the request of Republicans. His visit was coordinated without the Obama administration’s knowledge, deepening tensions between two leaders who have never shown much affection for each other.
Jeremy Ben-Ami, president of the liberal Jewish advocacy group J Street, said Netanyahu was “crossing some lines that haven’t been crossed before and is putting Israel into the partisan crossfire in a way it has not been before.”
The largest pro-Israel lobby in the U.S., the American Israel Public Affairs Committee, has tried to play down the partisanship.
“AIPAC welcomes the prime minister’s speech to Congress, and we believe that this is a very important address,” said spokesman Marshall Wittmann.
Netanyahu is scheduled to speak Monday at AIPAC’s annual policy conference. The Obama administration will be represented at the event by U.N. Ambassador Samantha Power and national security adviser Susan Rice.
Nearly a dozen Democratic lawmakers plan to sit out Netanyahu’s speech to Congress. Obama has refused to meet Netanyahu during his visit, with the White House citing its policy of not meeting with foreign leaders soon before their elections.
