The White House said today that world powers are united in their effort to negotiate a nuclear deal with Iran and warned the Congress over opposing the diplomatic efforts, noting that American people do not want a march to war.

Asserting that Iran rejected the unified proposal form the six-nation P5 Plus One group on Tehran's nuclear weapons program, the White House on Tuesday said diplomatic option continues to remain even if the military option is not off the table when it comes to Iran.

"The P-5-plus-1 were unified on the proposal that was put forward and that the Iranians did not accept that proposal -- and that's a statement of fact," White House Press Secretary Jay Carney told reporters at his daily news conference.

The negotiations between Iran and the P5 plus One, comprising of the US, France, Britain, China, Russia and Germany would resume in Geneva on November 21 and 22
