For 20 years, the White House stood guard over the peace process, reserving for itself the role of stewarding Israel and the Palestinians to a resolution of their conflict. Like some Godfather, the US expected unquestioning loyalty.
But Washington's primacy in the relationship with both the Israeli and Palestinian leaderships is unraveling at astonishing speed.
The crisis has been building for six years. Barack Obama arrived at the White House just as Israel elected one of the most right-wing governments in its history, led by Benjamin Netanyahu.
At their first meeting Obama reportedly told his Israeli counterpart "not one more brick," insisting on a settlement-building freeze so that Washington could revive the long-stalled Oslo peace process.
Netanyahu soon defied the president, and has been doing so ever since. The latest humiliation -- the final straw, according to White House officials -- was Netanyahu's success in engineering an invitation to address the US Congress next month.
By all accounts, the Israeli prime minister hopes to undermine a key plank of Obama's foreign policy -- negotiating a deal with Iran on its nuclear program -- by persuading Congress to stiffen sanctions against Tehran. That risks a crisis that might ultimately drag the US into war with Iran.
But Netanyahu is not alone in testing Obama's power. The Palestinian president, Mahmoud Abbas, has also recently chosen to bypass the White House. After years of fruitless waiting, he has pinned his hopes on new international sponsors who can help him achieve his goal of statehood.
Ignoring White House injunctions, he has pressed ahead with resolutions at the United Nations and has now deployed his doomsday weapon: joining the International Criminal Court (ICC) at the Hague. Israelis are calling this a "diplomatic intifada" and urging the US to cut its $400 million annual aid to the Palestinian Authority.
Just as with a mafioso boss, Obama is in trouble if he can no longer inspire fear, let alone respect. But the problem is all his own making.
For six years, Netanyahu "spat in our face," as one White House official memorably observed of the latest crisis, and paid no discernible price for his impudence. Conversely, Abbas has done everything the Obama administration asked of him, and has precisely nothing to show for his efforts.
Both the Israeli and Palestinian leaderships believe separately that they have core -- even existential -- interests that the White House is now an obstacle to realizing.
Abbas' disobedience is born of necessity. Aware that the US will never act as honest broker in the peace process, he has been forced to turn to international forums, where Washington's power is weaker, in the hope of forcing Israel to concede a small Palestinian state.
Netanyahu's move, meanwhile, is based on the risky calculation that he can maneuver the US into a confrontation with Iran to maintain Israel's regional domination. In doing so, he has made two dubious assumptions.
The first is that he can wait out Obama, who has little more than a year and a half left in office. Netanyahu is betting on a hardline Republican successor who will follow his lead against Tehran.
He may well be disappointed. Even assuming a Republican wins, their hawkish campaign rhetoric on Iran will be fiercely tested by the limitations of office. The US intelligence agencies and military will be instructing the next president in the same cold political realities faced by Obama.
