No, have you seen that before this picture was taken.
By
that do you mean a chubby Asian man shaking hands with an old Asian man??
Yes, I have seen that.
Or do you mean Moon Jae-in shaking hands with Kim Jong-un in the JSA?
No, I had not seen that before that picture was taken. It was historic, as was the Trump Kim summit.
The "agreement" is not so historic. Does that handshake mean this time will be different? I hope so, but I doubt it.
With NK we are past the point of "Trust but verify". It is "Distrust until verified".
