But it's not just Trump.
It's pretty much every American since the Korean War.
Most Americans, save for a few scholars and still-living witnesses, are unaware that the United States killed hundreds of thousands of Korean civilians through carpet bombing pretty much the whole country to selective mass shootings of refugees.
Mehdi Hassan does a good roundup of scholars on this national ignorance in The Intercept. A chunk of that comes from a Washington Post essay by Blaine Harden.
Yes, Kim Jong-un, his father and grandfather are and were tyrants of the worst degree, rabid in their hatred of America.
So are many North Koreans.
And yes, much of the latter-day hatred is stoked by the Kims' propaganda machinery.
But none of this would have been possible without the very real American attrocities committed upon the Korean people.
If the ever-growing possibility of a nuclear war on the Korean peninsula is to be halted and even reduced, it will have to include an American acknowledgment of its war crimes.
And that has to start with an apology from the United States.
So we need to consider our own hypocrisy when belittling Trump for his willful ignorance of history.
Such intellectual laziness could lead to a nuclear nightmare.
For those who survive, it will be easy to blame Trump.
But a hard look into a mirror will be equally warranted.
