WASHINGTON (JTA) — President Barack Obama’s refusal to accept Israeli Prime Minister Benjamin Netanyahu’s ostensible recommitment to a two-state solution to the Palestinian-Israeli conflict has watchers of the U.S.-Israel relationship wondering if the recent crisis is a mere speed bump or a sign of a deeper shift in ties between the countries.

Netanyahu moved quickly last week to emphasize that his statement on the eve of his reelection that no Palestinian state would be established on his watch did not represent a policy shift away from a two-state solution. But Obama administration officials were unwilling to accept that clarification, a point the president emphasized in a press conference Tuesday when he said that differences with Israel were “substantive” and not easily papered over.
