Japan Times reports: U.S. President Donald Trump has said Japan should have shot down the North Korean missiles that flew over the country before landing in the Pacific Ocean earlier this year, diplomatic sources have said, despite the difficulties and potential ramifications of doing so.
The revelation came ahead of Trump’s arrival in Japan on Sunday at the start of his five-nation trip to Asia. Threats from North Korea’s nuclear weapons and missile development programs were set to be high on the agenda in his talks with Prime Minister Shinzo Abe on Monday.
Trump questioned Japan’s decision not to shoot down the missiles when he met or spoke by phone with leaders from Southeast Asian countries over recent months to discuss how to respond to the threats from North Korea, the sources said.
The U.S. president said he could not understand why a country of samurai warriors did not shoot down the missiles, the sources said. [Continue reading…]
Joe Cirincione writes: The number one reason we don’t shoot down North Korea’s missiles is that we cannot.
Officials like to reassure their publics about our defense to these missiles. Japanese Chief Cabinet Secretary Yoshihide Suga told his nation after last week’s test, “We didn’t intercept it because no damage to Japanese territory was expected.”
That is half true. The missile did not pose a serious threat. It flew over the Japanese island of Hokkaido, landing 3700 km (2300 miles) from its launch point near North Korea’s capital of Pyongyang.
The key word here is “over.” Like way over. Like 770 kilometers (475 miles) over Japan at the apogee of its flight path. Neither Japan nor the United States could have intercepted the missile. None of the theater ballistic missile defense weapons in existence can reach that high. It is hundreds of kilometers too high for the Aegis interceptors deployed on Navy ships off Japan. Even higher for the THAAD systems in South Korea and Guam. Way too high for the Patriot systems in Japan, which engage largely within the atmosphere.
All of these are basically designed to hit a missile in the post-mid-course or terminal phase, when it is on its way down, coming more or less straight at the defending system. Patriot is meant to protect relatively small areas such as ports or air bases; THAAD defends a larger area; the advanced Aegis system theoretically could defend thousands of square kilometers.
But could we intercept before the missile climbed that high? There is almost no chance of hitting a North Korean missile on its way up unless an Aegis ship was deployed very close to the launch point, perhaps in North Korean waters. Even then, it would have to chase the missile, a race it is unlikely to win. In the only one or two minutes of warning time any system would have, the probability of a successful engagement drops close to zero. [Continue reading…]
