With Vice President Pence en route to the Korean Peninsula, North Korea attempted a missile launch that failed on Saturday evening (ET), the South Korean government said.
What it means: Inside of 100 days of his presidency, Trump faces a huge provocation, and a massive challenge to diplomatic and military machinery that are new to his teams. North Korean leader Kim Jong-un appears to want war, and China has warned the tensions could spiral out of control. It's Trump's biggest test.
North Korea held a military parade earlier today, debuting what appeared to be the country's new submarine-based and long-range missiles. The parade also celebrated the 105th birth anniversary of Kim Il-sung, North Korea's founding president.
Why it matters: The military parade, particularly the presentation of the nation's new ballistic missiles, is the latest display of military force as tensions continue to grow between North Korea and the US.
