Secretary of State John Kerry said Thursday there is no end to the diplomatic challenges America faces, but he is absolutely certain the world is safer for having reached a nuclear accord with Iran.
He said reaching that deal allows the U.S. to tackle other priorities, including Syria.
"Iran was hurtling towards an unaccounted for, uninspected, full-fledged nuclear program with high levels of enrichment where they had enough enriched material to make 10 to 12 bombs," Kerry told CNBC's "Squawk Box" at the World Economic Forum in Davos, Switzerland. "Now, frankly, at Iran's consent and agreement, they have rolled that back."
The international community ended sanctions on Iran related to its nuclear program earlier this month after determining that Tehran met the terms of a deal reached last year. Those terms included shipping enriched material to Russia, drawing down its stock of centrifuges and destroying a plutonium reactor.
Long-standing U.S. sanctions related to Iran's support for terrorist groups and its human rights record remain in place. The Treasury Department this week imposed new sanctions on 11 companies and individuals who the United States says helped to advance Iran's ballistic missile program.
Shortly before that, Iran released four American prisoners in exchange for the release of seven Iranians held for violating U.S. sanctions and an agreement to drop international arrest warrants for 14 others.
