Biden broke all ties with North Korea after Trump. Reverting to the old demand to denuclearize before for any negotiations and imposing more sanctions.
As we have learned from Ukraine. no sane country should ever give up their nukes because they become a prime target for invasion. If Ukraine still had nukes Russia would never have invaded.
Now I’m not a an NK fan but I’m not sure why people think pushing NK away would make them more friendly. Unlike the past where American sanctions spelled doom and America could bend any country to their will, China and Russia are now picking up the countries America pushes away.
