Of course...
Simply return to the same negotiation pattern we used prior to what the Bush, Clintoon, Bush, Obama’s all used.
IE: we are willing to negotiate your formal end to the Korean War and eventual absorption into the South Korea. Anything provocation will be met with an overwhelming show of force.
Also, re-install nuclear weapons into South Korea. Build and field neutron bombs. Target the major population centers, manufacturing sites, and military bases. And let it be known that we desire nothing more than an excuse to exterminate all life in North Korea.
They’ll shut up if confronted with that.
