The U.S. and other Western countries are often trying to isolate Iran, but this week the country is in the international spotlight as it hosts a summit of 120 nonaligned nations.

U.N. Secretary-General Ban Kim-moon decided to go, ignoring the advice of Israel and the U.S. He promised to deliver a tough message, but others are skeptical, arguing that his visit plays into the hands of the Iranians and to U.N. detractors in Washington.

The United Nations role in Syria is changing and so too is its personnel. Secretary General Ban Ki Moon is expected to tap a veteran U.N. troubleshooter to take over from International Envoy Kofi Annan. At the same time, U.N. military observers are wrapping up their mission. NPR's Michele Kelemen has the latest.

Republican presidential candidate Mitt Romney says America's national security priority should be preventing Iran from acquiring a nuclear weapon, and he was talking tough about this in his recent stop in Jerusalem.

"History teaches with force and clarity that when the world's most despotic regimes secure the world's most destructive weapons, peace often gives way to oppression, to violence, or to devastating war," Romney said. "We must not delude ourselves into thinking that containment is an option."

U.S. diplomats were relieved this weekend when China allowed a prominent dissident, Chen Guangcheng, to fly to New York with his family.

China, too, is presumably happy that Chen is no longer in the country doing his advocacy work. Chinese exiles tend to fade into obscurity when they leave the country, and Beijing might be counting on that to happen with Chen.

But social media may be changing this equation.
