As the relationship between United States and Israel hits a new low, a senior Obama official has reportedly called the Israeli PM Benjamin Netanyahu, a "chickenshit" and "coward."

"The thing about Bibi [Netanyahu] is, he's a chickenshit," said the senior Obama administration official, referring to the Israeli PM by his nickname, reported The Atlantic.

The official further elaborated on the Israeli PM saying:

"The good thing about Netanyahu is that he's scared to launch wars. The bad thing about him is that he won't do anything to reach an accommodation with the Palestinians or with the Sunni Arab states.

"The only thing he's interested in is protecting himself from political defeat. He's not [Yitzhak] Rabin, he's not [Ariel] Sharon, he's certainly no [Menachem] Begin. He's got no guts."

The Israeli PM has allegedly said to have "written off" the Obama administration at several occasions recently and plans to directly address the American people should an Iran nuclear deal be reached.

Meanwhile, the Obama administration officials have expressed their fury over Netanyahu's defiant approach at pursuing settlement policies in the West Bank undermining Secretary of State John Kerry's peace process.

"The Israelis do not show sufficient appreciation for America's role in backing Israel, economically, militarily and politically," said Abraham Foxman, the head of the Anti-Defamation League.

Another senior Obama official has alleged that it is too late for Netanyahu to panic about Iran.

"It's too late for him to do anything. Two, three years ago, this was a possibility. But ultimately he couldn't bring himself to pull the trigger. It was a combination of our pressure and his own unwillingness to do anything dramatic. Now it's too late," said the official, reported The Atlantic.

In the wake of the full-blown crisis between the two nations, it is also rumored that the Obama administration might withdraw diplomatic cover for Israel at the United Nations.

It remains to be seen what emerges when the two world leaders meet at the UN next year, when the President of the Palestinian Authority, Mahmoud Abbas will possibly seek full UN recognition for Palestine.
