North Korean State Television (their version of Fox News), aired footage of Trump saluting one of their generals in Singapore. Apparently 'Comrade' Trump had no idea what the proper protocol was, and just gave this goofy salute back in return. Naturally, the North Koreans are absolutely gleeful at yet another propaganda coup.given so willingly by America's own 'Dear Leader'.
The salute occurs at the 55-second mark.
And this twitter user gets it.
