(CNN) -- The failure of the P5+1 (the United States, United Kingdom, France, China, Russia plus Germany) to reach agreement with Iran Saturday in Geneva is a good thing if it allows the United States and Israel to sort out what really divides them on the Iranian nuclear issue before negotiations resume in coming days. That the French -- not the United States -- seem to have taken the lead in stiffening the allies' demands with Iran is in itself a reflection of those differences. And while a high-ranking U.S. delegation headed to Israel Sunday to brief the Israelis on the talks, bridging the gap there won't be that easy.

Miller: An agreement Israel opposes would be unpopular in Congress
This world view poses enormous challenges for a @placeholder administration, partly because it's validated by Iran's own past rhetoric and actions and because Iran has tried to hide suspected military aspects of its nuclear program.
And they are going to be a rocky six months if Netanyahu concludes that the interim arrangements reached in Geneva work to @placeholder's advantage.
And @placeholder is already inclined to adopt the Israeli view that what's required now is more pressure on the mullahs rather than less, including additional sanctions.
And a @placeholder who believes the Americans aren't taking him seriously on Iran is certain to be withholding when it comes to the peace process.
To satisfy Israeli requirements, an interim agreement would have to do at least three things: first, avoid doing anything that dismantles the sanctions regime and removes real pressure on Iran to cut the final deal; second, make it impossible for @placeholder to use the next six months to advance in a significant way any of the aspects of its nuclear program -- not just to freeze Iran's program but to actually set it back significantly.
