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 Biden administration will significantly loosen federal mask-wearing guidelines to protect against COVID-19 transmission on Friday, according to two people familiar with the matter.
Russian President Vladimir Putin openly invaded the neighboring country of Ukraine on Thursday following weeks of overtures and discussions on keeping an incursion from happening. David Salvo, the deputy director for the Alliance for Securing Democracy, joined Cheddar to go into the Russian leader's motivations. "What I'm sure he understands is that his invasion of Ukraine in 2014 probably ended the discussion of Ukraine joining NATO, even if publicly we won't admit that, that's just the reality. And I'm sure that President Putin understands that," he said, noting that Putin could be using the taking of Ukraine territory as leverage to gain more security concessions from the West.
Following Russia's incursion into Ukraine, the U.S. is warning businesses and major banks to brace themselves for cyberattacks. Lester Munson, a senior fellow at the National Security Institute, joined Cheddar News to break down what this means for financial institutions “So we need to be concerned about not just intentional Russian hacks against American entities but also what Russia is doing in Ukraine. Those things can impact us as well," he said
After weeks of talks and posturing in hopes of staving off an attack, Russia invaded Ukraine on Thursday, an incident that has already impacted the global economy, including the U.S.. Jason McMann, head of geopolitical risk analysis for Morning Consult, joined Cheddar’s Closing Bell to break down what investors might do to prepare themselves as the crisis continues. "I think there are a few things that we have our eye on over at Morning Consult that could cause the situation to become a bit more severe or unstable as far as market outcomes would be concerned," McMann said. "One of those things would be if the U.S. and the EU kind of moved in concerted fashion to block Russia from the SWIFT transaction system. So, I would say that's one thing that would be worth keeping an eye on."
