Here is a question for you. Do you seriously believe that President Donald Trump is in the picture below, taken at the NATO summit meeting today? Even in the NBA, does anyone ever take pictures and put the 6’3″ guy in front? I should note that I very much doubt that Turkish Prime Minister Erdogan is actually 6 feet tall, just as I refuse to believe that Emmanual Macron is genuinely 5’10” as some reports have had it.

Now, we can see how tall the Short Fake Trump is since we know that Macron’s actual height is, at most, 5’7″ tall.
Based on the available analyses, Emmanuel Macron’s height is most consistently reported as 5 feet, 7 inches. Two sources confirm this measurement: one from Business Insider ranking world leaders by height and another from a World publication specifically about the French President’s height.

I think it’s interesting they had Queen Máxima of the Netherlands, the woman in the funky green superhero jumpsuit, wearing something that obscured her footwear. However, since she is 5’8″, we can be confident that she is not wearing heels or she’d be towering over both Macron and the Short Fake Trump.
I await with interest the explanations of those who claim that there are no Trump body doubles and that it is simply an inability to understand the effect of camera angles accounting for the magic disappearing six inches of President Trump’s height.
UPDATE: further confirmation. The man in between Queen Maxima and the Short Fake Trump is King Willem-Alexander of the Netherlands. According to Schweizer Illustrierte, he is 6’0″ tall.
