those weren't icbm, they were irbm. the video floating around was proven true so it was really a irbm mirv non nuclear test, at mach 10. that's why it was slower than icbm, which can go mach 20 or more. it won't make much of a difference in the grand scheme of things. they could have used something else to the same effect and nato will still use long range missiles inside russia.
