Alarmingly, tensions between the United States and North Korea have again reached crisis proportions. The United States wants North Korea to curtail any further development of its nuclear weapons program, as well as to stop testing its missiles. North Korea evidently seeks to bolster its security by acquiring a sufficiently robust deterrent capability to discourage an attack by the United States. The unpredictable leaders of both countries are pursuing extremely provocative and destabilizing patterns of behavior. Where such dangerous interactions lead no one can now foresee. The risk of this tense situation spiraling out of control should not be minimized.
