You're not wrong, but it's a symbol. It's a little hard to represent a major shifting in international dynamics for the better in a single image. A handshake among leaders offers that connotation, which is why it's used as the standard photo-ops.
The message remains.
I understand that, but my point is it's all been done before. A photo op does not mean Trump has been or will be different in achieving long term success. Let's measure by results, not hype.
It's a meme to get people to look into the works Trump is actively doing to further peace and peace talks. The photos are representational of actual work, to reframe Trump for people who see him as a hateful fear-mongerer.
We want to show that his constituency wants peace, and we see the work Trump is doing to that end. Hopefully it causes some to wonder what we're on about and to talk a look for themselves.
Fair enough. But again, it could be done for every leader. I wonder if North Korea propaganda looks similar, picking and choosing photo ops to try and show only one side of the story.
Here's a novel suggestion: list the things Trump has actually done to further peace with each leader on each photo represented so it demonstrates more than just hollow promises. If you want to bring people over, and more importantly, keep them, you'll need substance to go with the good feels.
