During his latest Fox News interview, Donald Trump briefly addressed the burgeoning crisis with North Korea, and expressed confidence in the United States’ position. “We have missiles that can knock out a missile in the air 97% of the time,” the president boasted on Wednesday, “and if you send two of them, it’s going to get knocked down.”
As the Washington Post explained this morning, this is plainly wrong.
The president speaks with confidence but descends into hyperbole. No single interceptor for ICBMs has demonstrated a 97-percent success rate, and there is no guarantee using two interceptors has a 100-percent success rate. Moreover, the military’s suggestion that it could achieve a 97-percent success rate with four interceptors appears based on faulty assumptions and overenthusiastic math.
The odds of success under the most ideal conditions are no better than 50-50, and likely worse, as documented in detailed government assessments.
This is not, however, one of those “let’s all laugh at the foolish man in the Oval Office” moments. Because if the president actually believes what he told a national television audience about the efficacy of the existing missile-defense system, his confusion may carry serious consequences.
