Now that North Korean leader Kim Jong Un has pledged to work toward the denuclearization of the Korean Peninsula, the focus will turn to Pyongyang's willingness to actually dismantle its nuclear weapons program under robust international verification.
Verification, analysts say, is key in achieving the "complete" denuclearization Kim promised during a historic meeting Tuesday with U.S. President Donald Trump in Singapore.
A joint statement issued after the first-ever U.S.-North Korea summit makes no reference to verification nor to a time frame to achieve denuclearization. But Trump said Tuesday a denuclearization process "will be verified" and that senior officials from the two sides will work out details.
