Do I sound like a conspiracy theorist if I say this sounds like a staff tweet? Many flags: "big", not very big, not the biggest in history... Democrats in the House - accurate language. huge flag! "Big step in the right direction" Not Trump vocabulary. And of course the most egregious: "Wall is under construction" Not "Finish the wall!"
The only trumpian thing about this is the weird capitalization.

I very much prefer video evidence.

You know what promises Kim made? I don't. Maybe he didn't promise not to fire small weapons into the sea.
You're right to point out that we don't know what he promised because Trump never had Kim put it in writing - he basically paid Kim for the vegetable remains of Otto Wambier, he cancelled troup exercises with SK and elevated KJU on the world stage in exchange for nothing. He claimed "total denuclearization," but ldo NK resumed nuclear proliferation just months after the summit.
