Over the next days, we'll learn more vital details about Tuesday's nuclear test by North Korea.
We'll discover how powerful the blast was -- Pyongyang's first test in 2006 was widely seen as a partial dud. Its second in 2009 was more impressive but still smaller than expected. Early estimates of Tuesday's blast suggest the North Koreans are beginning to master nuclear devices with substantial explosive power.
We'll likely learn if Pyongyang has built a nuclear weapon of enriched uranium, a major step in its ability to amass a much larger nuclear arsenal.
Most ominously, we may get hints about whether the North has made significant progress in developing a warhead small enough to fit atop a long-range missile and threaten the United States or its allies. A recent rocket launch was deemed a success by arms experts, meaning North Korea could eventually lob a nuclear-tipped missile as far as the United States mainland.
This latest nuclear test is significant, too, for another reason: It buries any hopes that new leader Kim Jong Un would ratchet down the bluster and threats and try harder to feed his starving people.
U.S. pressure -- or inducements of food and other aid -- won't force the regime to back down. Been there, tried that. Again and again.
North Korea's main ally, China, still holds the greatest leverage: The Chinese can slow food and oil deliveries, crimping Pyongyang's trade even more. Incoming Chinese President Xi Jinping has said he wants "a new type of relationship" between the U.S. and China. Here's a start: Persuade the North Koreans to back off.
Otherwise, there's one inescapable conclusion from this nuclear test. There will be more. The North Korean threat is growing. There's nothing on the horizon to stop it.Tweet
