Iran’s test last week, almost certainly of a medium-range Khorramshahr-class or variant missile, is a very big deal.

For a start, with Secretary of State Mike Pompeo attending a NATO foreign ministers meeting in Brussels on Monday, Iran has given the U.S. ammunition to push for new sanctions against it. This isn’t just some neocon conspiracy. Iran’s ballistic missile program has no peaceful purpose, and no other purpose than to give the Islamic republic the means to launch nuclear strikes. Second, although Europeans are skeptical of President Trump’s Iran nuclear deal withdrawal, they share U.S. concerns over Iran’s missile program.
