OP’s photo is my favorite, so I will have to mention my second favorite (though calling it a “favorite” feels off).

This photo was taken in 2003 in Iraq. This man is comforting his son. They are being held in an American camp. IIRC to this day we don’t know what happened to these two.

I think if I had to explain the last 25 years to a time-traveler, this would be the one photo I would choose.
