Iran is cooperating with North Korea on intercontinental ballistic missiles
Second, Iran works very closely with North Korea on its nuclear and missile programs. Consequently, it has the ballistic missile capacity to launch weapons of substantial size and intercontinental range against us, or to orbit satellites above us.
So troubling is this capability — in the hands of either Iran or North Korea — that nine years ago, based on the ability of North Korea’s Taepodong missile to carry a nuclear warhead to intercontinental range, the current secretary of defense, Ashton Carter, and a prominent former secretary, William Perry, urged in a 2006 oped a pre-emptive strike against the then-new North Korean long-range missiles on their launch pads. As the two secretaries put it then, “Intervening before mortal threats to U.S. security can develop is surely a prudent policy.” Their view was that our ballistic missile defense capabilities were unproven and should not be relied upon for such an important task. “Diplomacy has failed,” they said, “And we cannot sit by.”
