Kim was initially considered inexperienced. However, he quickly demonstrated his determination to consolidate his power by having his uncle executed and his potential rivals purged. Many were afraid of a second Korean War after his recent string of missile and nuclear tests.
Kim changed gears once again, and held landmark nuclear disarmament summits alongside then-U.S. President Donald Trump. However, their diplomacy was ruined by disputes over U.S.-led Sanctions. With the growing pandemic and sanctions, Kim sealed off his country’s borders to try and fix its failing economy.
Here’s a look back at Kim’s key moments as he enters his second decade of power.
