North Korea has just pulled off an impressive dual feat -- the successful test both of an intercontinental ballistic missile and an atom bomb in the 6-kiloton range.
Pyongyang's ruler, 30-year-old Kim Jong Un, said the tests are aimed at the United States. So it would seem. One does not build an ICBM to hit Seoul, 30 miles away.
Experts believe North Korea is still far from having the capability to marry a nuclear warhead to a missile that could hit the West Coast. But this seems to be Kim's goal.
Why is he obsessed with a nation half a world away?
America has never recognized his, his father's or his grandfather's regime. We have led the U.N. Security Council in imposing sanctions. We have 28,000 troops in the South and a defense treaty that will bring us into any war with the North from day one, and a U.S. general would assume overall command of U.S. and Republic of Korea troops.
We are South Korea's defense shield and deterrent against the North.
And while America cannot abdicate her responsibility and role in this crisis, we should be asking ourselves: Why is this our crisis in 2013?
President Eisenhower ended the Korean War 60 years ago. The Chinese armies in Korea went home. Twenty years ago, the Soviet Union collapsed, Russia abandoned communism and ceased to arm the North, and Mao's China gave up world revolution for state capitalism.
Epochal events. Yet U.S. troops still sit on the DMZ, just as their grandfathers did when this writer was still in high school.
Why? North Korea represents no threat to us, and South Korea is not the ruined ravaged land of 1953. It has twice the population of the North, an economy 40 times the size of the North's, and access to the most modern weapons in America's arsenal.
Why were U.S. troops not withdrawn from Korea at the end of the Cold War? Why should we have to fight Seoul's war if Pyongyang attacks, when the South is capable of fighting and winning its own war?
Why is South Korea's defense still America's obligation?
Had the United States moved its soldiers out of South Korea, and its planes and ships offshore, and turned over to Seoul responsibility for its own security, would the North be building missiles that can hit the United States?
Undeniably, Kim Jong Un runs a tyrannical, wretched regime. But its closest neighbors are South Korea, Japan, Russia and China.
Why is Kim Jong Un not primarily their problem, rather than ours?
Had we departed 20 years ago, the South would have built up its own forces to contain the North. Instead, we have allowed it to remain a strategic dependency. And the same holds true for Japan.
