Taking Nuclear Korea Seriously The rogue regime will soon have an arsenal that can hit Chicago.

North Korea conducted its fifth nuclear test Friday, following three missile tests on Monday and about 20 so far this year. The accelerating pace of the Kim Jong Un regime’s nuclear and missile testing shows its determination to threaten Japan, South Korea and the U.S. homeland with nuclear weapons. The question is whether the West is capable of a more determined response.

Every nuclear test leaves forensic clues, and analysts are suggesting this was Pyongyang’s most successful, with an apparent yield of 10 kilotons. This is the North’s second test this year, suggesting it has an ample supply of nuclear material from its restarted plutonium reactor and enriched uranium.

The North said it tested a miniaturized nuclear warhead that could be placed on a missile. True or not, we know its scientists had access to a Chinese design for a partially miniaturized weapon through the proliferation network of Pakistani scientist A.Q. Khan. The U.S. believes the North already has small enough warheads to fit on short-range missiles aimed at South Korea.

The North’s workhorse Nodong missile now has a range of more than 600 miles. In June it launched a medium-range Musudan missile from a road-mobile launcher, which makes it hard to detect and destroy. North Korea recently launched a missile from a submarine into the Sea of Japan at a range of 300 miles. This means Pyongyang now has a second-strike capability if the world tried a preventive attack to destroy its nuclear weapons.

A growing worry for the U.S. is the North’s new KN-08 intercontinental missile with the range to hit Chicago. In February the North used a similar rocket to launch a small satellite into space. Significant challenges remain, including a warhead that could withstand the vibration and temperature changes of a long-range missile flight. But the North has repeatedly solved technical problems more quickly than expected.

All of this means the window to prevent the North from becoming a global nuclear menace is closing while the proliferation risks are growing. The North has cooperated with Iran on missile development in the past and may share its nuclear secrets.

Right on cue, the world’s powers condemned the missile launch. And President Obama promised “additional significant steps, including new sanctions to demonstrate to North Korea that there are consequences to its unlawful and dangerous actions.”

Yada, yada, yada. Why should Kim and company fear such words?

Sanctions get passed as a ritual but are never enforced enough to matter. Earlier this year China began to enforce new sanctions, but Beijing let trade with the North resume after Seoul decided in July to deploy the U.S. Thaad missile-defense system. Only sanctions that imperil the regime will force the North to freeze its nuclear program, and Beijing has never been willing to risk undermining its client state. CONTINUE AT SITE
