South Koreans responded with a mix of optimism and worry Tuesday after President Trump announced he would suspend joint military exercises with South Korea as Kim Jong-un considers how to dismantle North Korea's nuclear arsenal.

But Trump's unexpected announcement that he would stop joint military drills made some of America's allies in South Korea uneasy, according to Martyn Williams, editor at NorthKoreaTech.org.
"The right wing in South Korea is already not very pleased with these military drills stopping taking place," Williams said in an interview with Cheddar.
The president's statement, which appeared to be an off-the-cuff comment in a discussion with reporters after his meeting with Kim, was not part of the joint statement signed by the two leaders. The United States and South Korea conduct regular war games to prepare for the possibility of a conflict with North Korea, and there are about 28,500 U.S. troops stationed in South Korea.
Trump had said he hoped to strike a deal with Kim to eliminate North Korea's nuclear program, and touted the "very comprehensive" statement the leaders agreed to at the summit. But Williams said denuclearization will take more negotiations.
"I think it was a good first step, but what comes next is the most important thing," Williams said.

The United Nations High Commissioner for Refugees (UNHCR) has reported that an estimated one million people have fled from Ukraine since Russia invaded. Christopher Boian, senior communications officer at UNHCR, joined Cheddar News to report on the current refugee crisis and what the world might expect if conditions continue to worsen. "We have planning figures that forecast as many as four million people could be forced to flee Ukraine," he said. "But that very much depends on how the conflict underway in that country at the moment unfolds in the days and possibly weeks ahead."
Under the U.S. Renewable Fuel Standard (RFS), corn-based ethanol has been mixed into gasoline sold at pumps in the U.S. since 2005, when a policy was enacted aimed at reducing emissions. Corn-based ethanol had been thought to be a relatively greener energy source compared to other biofuels, but now, a new study published in the Proceedings of the National Academy of Sciences reports it may be actually worse for the climate than straight gasoline. Tyler Lark, an assistant scientist at the University of Wisconsin-Madison's Center for Sustainability, joined Cheddar News' Closing Bell and discussed the pushback against the study. "Essentially when you need to produce more corn to meet the demand for use as ethanol as fuel, farmers respond and they switch more crops like soybeans and wheat into corn," Lark said. "They also bring more land into production, so things that used to be pasture grassland, and both those activities are associated with increased greenhouse gas emissions."
