“And what exactly did he give in return?”
Agreed to give up nukes.
Now if he reneges on his agreements, then Trump can cancel out also.
That is how that works.
You did not know that?
The exact wording was, "Reaffirming the April 27, 2018 Panmunjom Declaration, the DPRK commits to work toward complete denuclearization of the Korean Peninsula." I don't see a specific agreement to give up his nukes in that.
Now if he reneges on his agreements, then Trump can cancel out also.
At what point do you decide he's reneged?
That is how that works.
You did not know that?
Just like that, huh?
