Once again, Donald Trump has displayed an apparent lack of interest in his own job - via his own Twitter account.
He was helpfully providing his own reporting on the meeting with German Chancellor Angela Merkel.
(Presumably in response to all those FAKE NEWS videos of him refusing to shake her hand...)
...And he tweeted:
That's just...not how it works.
Thankfully, former US ambassador to NATO, Ivo Daalder, helpfully tweeted (to the President of the United States):
Yes, that is the President of the United States of America, being schooled (publicly) on how NATO works.
