You’ve seen the news — Korea has apparently set off an underground nuclear explosion. (If not, scan down the page.) Much is in flux at the moment, but here’s a good start-up analysis from Josh Marshall.

North Korea’s nuclear program has been a problem for US presidents going back to Reagan, and the conflict between North and South has been a key issue for US presidents going back to Truman. As recently as 1994, the US came far closer to war with North Korea than most Americans realize.

President Clinton eventually concluded a complicated and multipart agreement in which the North Koreans would suspend their production of plutonium in exchange for fuel oil, help building light water nuclear reactors (the kind that don’t help making bombs) and a vague promise of diplomatic normalization.

President Bush came to office believing that Clinton’s policy amounted to appeasement. Force and strength were the way to deal with North Korea, not a mix of force, diplomacy and aide. And with that premise, President Bush went about scuttling the 1994 agreement, using evidence that the North Koreans were pursuing uranium enrichment (another path to the bomb) as the final straw.

Remember the guiding policy of the early Bush years: Clinton did it=Bad, Bush=Not whatever Clinton did.

All diplomatic niceties aside, President Bush’s idea was that the North Koreans would respond better to threats than Clinton’s mix of carrots and sticks.

Then in the winter of 2002-3, as the US was preparing to invade Iraq, the North called Bush’s bluff. And the president folded. Abjectly, utterly, even hilariously if the consequences weren’t so grave and vast.
