Early on in Donald Trump’s presidency, he faced a unique problem. Tensions began running high between the United States and North Korea, and we we unsure of the extent of their nuclear capabilities.

Fortunately for the former President, he was surrounded by people who knew what they were doing, even if he was in hopelessly over his head. He was flush with well-experienced staff. He had plenty of folks around him with in-depth knowledge of the government.

If it weren’t for this surplus of skill, he might have been in big trouble. One perfect example of that is a situation he found himself in with his former chief of staff, John Kelly. Kelly was a former Marine General before he came to work for Trump.

During the nuclear tensions with North Korea, Kelly came to Trump to warn him that Guam was particularly vulnerable to a strike. Such an act would have been terrifying, and yet Trump shrugged it off, saying “Guam isn’t America.”

Now, it’s already bad enough that Trump thought it was no big deal since it didn’t affect the US mainland and people he considers Americans. But Guam has been a US territory for 125 years. Their currency is the US Dollar. You grew up going to school with Guamanian kids.

Saying Guam isn’t America is essentially the same as saying Puerto Rico isn’t part of America. Oh, he wait, he had to be told that too.

America needs to be able to count on having a leader who at least knows what our country is made up of. I’m sure, in fact, that if John Kelly corrected Trump in the moment, that Donnie probably got into a heated argument about it. Because Trump is never just wrong. He is angrily wrong. He is defiantly wrong.

He’s pretty sure that you’re the one who’s wrong, because he’s so smart that he couldn’t possibly be wrong.

This had to be just one of a million moments while working for Trump that John Kelly — or anyone in his circle — silently shook their head and resigned themselves to just letting him think what he wants, then cleaning up the mess.
