Minju Joson Tuesday observes in a bylined commentary in this regard:

What Lubers said brings into bolder relief the fact that the U.S. is still deploying nukes in Europe.

The U.S. moves to modernize nuclear weapons while mocking and deceiving the world are aimed to seek its strategy for world supremacy by dint of nukes, the commentary says, and goes on:

The situation goes to prove that it is impossible to realize the world without nuclear weapons as long as the U.S. regards them as an effective means for world supremacy.

In order to realize the dream of mankind to live in a safe world free from nuclear threat it is necessary for the U.S. to take the lead in the efforts for denuclearization as it possesses the biggest number of nuclear weapons, has the precedent of using them and poses biggest nuclear threat to humankind while brandishing a nuclear stick at will.

The U.S. had better opt for denuclearization to meet the unanimous requirement of mankind, not practicing a black art with nukes.
