At President Donald Trump's first official trip abroad, there was a moment where he pushed aside Dusko Markovic, the prime minister of Montenegro, as he moved to the front of a group of the leaders . Many body language experts around the world analyzing his body language, especially in that moment [2, 3].
Watch the video where Trump pushes past Montenegro prime minister, Duško Marković
In the video above, you can clearly see that Mr Trump doesn't like the Montenegro PM, and you can see it when he first touches Duško Marković. The way he turns his head after the push and his facial expressions seems that he's some kind of angry about him or even ironic, maybe because Marković left him behind or Trump acts in primal level, where subconsciously believes that Marković is somehow above him, the 'superior' male who got the attention from everyone so he must 'put him down'.
The way he acts after that, seems that he stands with pride, that the job is done. However, according to bodylanguagesuccess.com, the way he stands with his hands in a fig-leaf (aka genital guarding) position, is 'in a beta emotional state and a part of his psyche knows he has over-stepped, thus he is (subconsciously and momentarily) down-regulating his aggressiveness', but I don't believe that. I think that he's posture says that he is proud, this posture is more of a leader than a beta male who tries to step back and calm things down. However, he was rude.
Here is the same video from another angle.
