Our Missile Defenses Go to 11
Despite spending tens of billions of dollars on missile defense over the last 30 years, the United States remains unable to shoot down North Korean ICBMs.

I usually write longer, detailed essays for this column but today’s submission is simpler. And it has a simple message. Missile defense will not protect the United States from North Korean missiles. I know a lot of people think the opposite is true. Even President Donald Trump has asserted we have a 97 percent chance of shooting down a North Korean intercontinental ballistic missile (ICBM). But, as they say, “um, no.”
It would make sense for you to scratch your head and ask how can we have spent tens of billions of dollars over 30 years and still not be able to shoot down a couple of North Korea missiles. But, sorry, we can’t.
This is true for a whole host of reasons, but let’s get right to the chase. Our missile defenses don’t work all that well (better than they used to, but far from reliable and very far from perfect) and we don’t have very many of them. It is like the old joke about the married couple. The wife complains “the food at this restaurant is terrible!” To which her husband responds: “Yeah, and the portions are small, too.”
Current U.S. military planning would shoot four ground-based interceptors (GBIs) in Alaska or California at each incoming North Korean ICBM. Do the math. We shoot four at each incoming missile because each interceptor has about a 25 percent chance of working: i.e. hitting its target. And that assumes everything goes right. So far, however, little goes right for our GBIs and none have ever taken down an ICBM in a realistic, real-time, no-notice test. In fact, the reason the United States purchased so few GBIs in the Obama years is because the ones we had already purchased did not work all that well. Time and money were needed to fix major systemic problems. They’re better now, but still far from perfect.

China’s political future will be shaped between now and next October. As the Communist Party enters its intense “campaign season” to prepare for a major political transition in 2027, reading Beijing's actions and responses may become more difficult as domestic politics weigh on its behavior more than usual.

- Caught in the Middle: Chinese Biotech Firms’ Divergent Responses to U.S. SanctionsCommentary
Chinese biotech companies have been on the receiving end of U.S. economic coercion. Yet their responses have differed significantly because firm and state interests are not uniformly aligned. For Washington, treating all Chinese tech firms the same, irrespective of their actual interests, risks pushing them farther into Beijing’s corner.

Across Asia, China is better positioned to withstand energy shocks from the fallout of the Iran war. Its abundant coal capacity can ensure stability in the near term. Yet at the same time, the country’s energy transition away from coal will make it even less vulnerable during the next shock.
