US intelligence estimates and experts outside government are busily downplaying Iran’s ability to launch ICBMs, much less to do so against American targets.

To build effective ICBMs, which soar out of the atmosphere and into space, Iran would have to overcome hurdles including developing a re-entry vehicle with heat shielding that can survive a fiery descent into the atmosphere, and a guidance system to keep the missile on target.

Iran has been launching satellites into orbit for years. Developing a reentry capability is a straightforward engineering task that lots of nations worked out decades ago, including such allies of Iran as Russia and the PRC. Indeed, Iran’s ballistic missile launches against Israel, as pointed out by ralflongwalker in another venue, already gives it most of the heat-shielding capability it needs for reentry after intercontinental flight. It’s an engineering refinement, now, not a de novo capability.

Iran’s ability to put its own satellites into orbit on its own rockets—much less its ability to target those Israeli sites—gives it already most, if not all, of the guidance system it needs, especially given the large footprint of its targets–our population centers.

Those downplayers plainly don’t understand the men of the Iranian government. In order to destroy us—the Great Satan—it would be necessary only to destroy our major cities with their populations and financial centers. Or even more easily, simply to detonate nuclear-driven EMP over us.
