Not entirely dominated. The "power move" pull that Trump does didn't happen, but he still turned Trudeau's hand to the bottom. Trump literally "taking the upper hand".
There's a handful of them.
Upper-hand - Trump got that one.
Double-hand - Both of them did it, both saw that they did it, and both let go (one double-hand is a power move, but both doing it ruins photos)
Here's Joe Biden doing the double hand:
Left-side-advantage - Trump got that one, too. The person on the left of the handshake (from the perspective of the audience) has a natural upper-hand -- if both are shaking their right hands.
Here's Putin using the left-side-advantage to get an upper-hand on Obama:
Pull-in - Trudeau got it, as your second picture shows. Trudeau is upright and made Trump lean in. Trump is huge on the pull-in, so that's pretty neat.
Last week, Trump used the pull-in AND double-hand on Shinzō Abe.
And yes, that list is real and I didn't make it up. And people do that shit. There's more like extending the time shaking hands when you think you're in a position of power (Trump did that to Abe as well...), but those are the big ones.
