North Korea

North Korea reopened a long-closed border hotline with South Korea, hours after U.S. President Donald Trump appeared to mock the North’s leader by saying he has a “bigger and more powerful” nuclear button than he does. The North’s decision to open the border phone line came a day after South Korea proposed high-level discussions amid a tense standoff over North Korea’s missile and nuclear programs.

The U.S. ambassador to the United Nations, Nikki Haley, warned North Korea against staging another missile test and said Washington would not take any talks between North and South Korea seriously if they did not do something to get Pyongyang to give up its nuclear weapons.

After a year of making threats and weapons advances, North Korea’s leader appears to be using the upcoming Winter Olympic Games in South Korea as a tool to blunt growing international pressure on Pyongyang while leaving his nuclear arsenal untouched. Kim Jong Un, in his annual New Year’s Day speech, called for reduced tensions on the Korean peninsula and flagged the North’s possible participation in the Games next month, just across the border in Pyeongchang.

Iran

Pro-government rallies in several Iranian cities drew thousands of marchers, following six days of rare unrest that took the country’s leaders off guard. State television broadcast live pictures of rallies in Kermanshah, Ilam and Gorgan, where marchers waved Iranian flags and pictures of Supreme Leader Ayatollah Ali Khamenei.

Iranian authorities are concerned that nationwide unrest will undermine the clerical establishment and want to stamp out the protests quickly, senior government officials say. But the person with the most to lose is President Hassan Rouhani.

VERBATIM: U.S. stands in solidarity with Iranian protestors

Commentary

Iran's protesters have legitimate grievances and President Hassan Rouhani needs to take them seriously, writes Amir Handjani. However, outsiders like President Donald Trump should be wary of expressing support for those out on the streets because it risks "tainting the protesters as foreign agents -- an easy tagline the regime uses to discredit dissidents."
