Donald Trump and Kim Jong Un are a lot alike.
Both appear to be overgrown children who failed to actually reach adulthood.
Both appear to vastly overestimate what their military resources can accomplish without killing hundreds of thousands of people.
Both appear to be unable to moderate their appetites for power, food, and blind loyalty.
Both have exceptionally poor haircuts.
Both laugh at very inappropriate times.
Both appear to think threats are an appropriate way to conduct international relations.
Both are idiots who should never be in charge of anything that affects others.
There are minor differences, though, between the two:
One thinks that a couple of missiles and a nuke or two will utterly destroy the other's nation, while the other thinks that a massive attack that actually could destroy the other's nation would go unnoticed and be celebrated by the rest of the world.
One speaks Korean, with a competence I cannot judge, while the other speaks English at about the 4th grade level.
