Yet Kim Jong Un has said he will never give up his nuclear weapons. He believes the survival of his dynastic regime depends upon them.
Hence we are headed for confrontation. Either the U.S. or North Korea backs down, as Nikita Khrushchev did in the Cuban missile crisis, or there will be war.
In this new century, U.S. leaders continue to draw red lines that threaten acts of war that the nation is unprepared to back up.
Recall President Obama's, "Assad must go!" and the warning that any use of chemical weapons would cross his personal "red line."
Result: After chemical weapons were used, Americans rose in united opposition to a retaliatory strike. Congress refused to authorize any attack. Obama and John Kerry were left with egg all over their faces. And the credibility of the country was commensurately damaged.
