North Korea agreed, last month, to freeze uranium enrichment and missile tests in exchange for large amounts of food aid from the United States. American officials thought they had an understanding, but then last week North Korea announced it would be launching a satellite using a long-range missile. As NPR's Mike Shuster reports from Seoul, all this is now threatening to overshadow next week's global nuclear security summit in Seoul, which President Obama is planning to attend.
Iran said Tuesday that it is unwilling to allow international nuclear inspectors to have complete access to a restricted military complex, called Parchin, which is near the capital Tehran. There are concerns that the complex may contain a facility designed to test explosives meant to trigger a nuclear chain reaction.
Republican presidential candidates this week — with the exception of Ron Paul — appeared to be trying to outdo each other in saying how tough they would be in dealing with Iran. Speaking before a pro-Israel group, they said President Obama has been weak — "feckless," in Mitt Romney's words.
Obama, meanwhile, was not impressed. He said he'd heard a lot of "bluster" and "big talk" about Iran, "but when you actually ask them specifically what they would do, it turns out they repeat the things that we've been doing over the last three years."
