Kerry: Unacceptable for Iran to Have Nuclear Weapon

Secretary of State John Kerry said on Friday he did not have high expectations that an upcoming presidential election in Iran would change the calculus over Tehran's nuclear program, repeating it was unacceptable for Iran to have a nuclear weapon.

At a joint news conference with German Foreign Minister Guido Westerwelle, Kerry said Iran needs to understand that international patience was waning over the nuclear program that Tehran says is meant for peaceful purposes.

"Every month that goes by gets more dangerous," Kerry said. Westerwelle also said more diplomatic talks were necessary.
