Redondo's article was about NK starting up their nuclear program again (the word "again" isn't accurate because it is something they never stopped doing under Trump and continue to do so under Biden). The aren't launching missiles right now though? So what is there to do? Trump didn't stop them so why should Biden?
To be honest, I agree with Tank that Biden could talk with Kim. Maybe even strike a deal but what is the point? In this highly partisan country, it will be just be slammed and criticized. And then revoked under the next president. Tensions will increase. People will say that NK was never abiding by the deal (and they would probably be right knowing Kim's character).
Oh and Redondo,we can still talk about Trump because not doing so isn't providing a full context of history and if there is one thing I know, we don't want to appear as if we are erasing history.
