Iran’s foreign minister says the country is open to resuming nuclear talks with the U.S. if guaranteed no further attacks.

Iran's nuclear program may get more difficult to monitor if no deal is reached with the United States. The U.N. nuclear watchdog has withdrawn its inspectors and nuclear experts believe Iran relocated more than 400 kilograms of highly enriched uranium—enough for 10 nuclear weapons—to a secret location.

In the wake of its brief but bruising war with Israel, Iran is walking the calculated, fine line of escalating nuclear ambiguity to deter future attacks while keeping one hand extended for diplomacy.
