The AIPAC Showdown: Obama vs. Bibi, Peres

The hottest ticket in town this season won't be any number of rehashed formal D.C. galas, but a courtside seat to a potentially defining moment in global security and the future of the Jewish state.

The American Israel Public Affairs Committee's annual policy conference comes at a critical juncture when Washington is tersely trying to stop Israel from launching a strike against Iran's nuclear facilities -- and Israel, which has encountered more head-butting than hand-shaking from this administration, will stress that time is of the essence in its decision.

And, buoyed by a pack of congressional supporters and thousands of AIPAC delegates, Israel is likely to stress just that to a hedging White House: It is our decision. If you're not going to act, we will.

The conference comes on the heels of Iran brusquely telling the latest group of International Atomic Energy Agency inspectors "no peeking" and threatening its own preemptive strikes against anyone who even thinks bad thoughts about the Islamic Republic.

AIPAC just announced this week that President Obama will be addressing the policy conference, which will be held March 4-6 at the Washington Convention Center.

Obama also addressed AIPAC last year; in 2010 the administration sent Secretary of State Hillary Clinton and in 2009 Vice President Joe Biden addressed the delegates.

As a senator running for the White House, Obama addressed AIPAC in 2008. "Part of our commitment must be speaking up when Israel’s security is at risk and I don’t think any of us can be satisfied that America’s recent foreign policy has made Israel more secure," he said back then. "…I will ensure that Israel can defend itself from any threat from Gaza to Tehran. Defense cooperation, defense cooperation between the United States and Israel is a model of success and it must be deepened."

Biden is being sent to Mexico and Honduras March 4-6, the White House announced today.

Obama, meanwhile, will be double-teamed at AIPAC: Both Israeli Prime Minister Benjamin Netanyahu and Israeli President Shimon Peres are coming to speak.

On March 5, Obama and Netanyahu meet at the White House. National Security Adviser Tom Donilon just returned from Israel in an effort to pave the way for those talks.

Netanyahu also addressed AIPAC last year, the night before he addressed a joint session of Congress. That May 2011 meeting between Obama and Netanyahu was described as "frosty," a day after Obama stated that a Palestinian state should be based on pre-1967 borders.

"Israel wants peace, I want peace," Netanyahu said after the Oval Office meeting. "But the only peace that will endure is one based on reality."

Netanyahu's impassioned address, sans teleprompter, to a packed Congress was much more warmly received -- presidents would wish to get such unified support in their State of the Union addresses.

Six months later, Obama was caught in a not-so-private exchange picked up by microphone at the G-20 summit in Cannes.

"I cannot stand him. He's a liar," Sarkozy said of Netanyahu.

"You're fed up with him? I have to deal with him every day," Obama replied.
