North Korea launched its first missile test since Election Day on Monday, strongly implying that it does not plan to play nice with President-elect Trump.

It isn’t a Donald Trump rally, however, but a protest by conservative supporters of impeached South Korean President Yoon Suk Yeol, who could become the East Asian democracy’s first sitting president to be arrested after he plunged it into political instability last month with his botched attempt to declare martial law.

Washington has provided extended deterrence, or a "nuclear umbrella," to Tokyo and Seoul in the face of Pyongyang's nuclear threat. It is a commitment made by the U.S. to deter and to respond potential nuclear and non-nuclear scenarios in defense of its East Asian allies.
