Some time ago, someone posted a good post on the speeds of ICBMs and IRBMs. Can't find it now.
Topol M in terminal phase is moving at about 7km per second.

ICBMs and SLBMs travel at 7km/s . No one has built any nuclear weapon faster than that. IRBMs travel at lesser speed.
In a MIRV,the main rocket motor (or booster) pushes a "bus" (see illustration) into a free-flight suborbital ballistic flight path. After the boost phase the bus maneuvers using small on-board rocket motors and a computerised inertial guidance system. It takes up a ballistic trajectory that will deliver a reentry vehicle containing a warhead to a target, and then releases a warhead on that trajectory. It then maneuvers to a different trajectory, releasing another warhead, and repeats the process for all warheads.
Minuteman III MIRV launch sequence: 1. The missile launches out of its silo by firing its first-stage boost motor (A). 2. About 60 seconds after launch, the 1st stage drops off and the second-stage motor (B) ignites. The missile shroud (E) is ejected. 3. About 120 seconds after launch, the third-stage motor (C) ignites and separates from the 2nd stage. 4. About 180 seconds after launch, third-stage thrust terminates and the post-boost vehicle (D) separates from the rocket. 5. The post-boost vehicle maneuvers itself and prepares for reentry vehicle (RV) deployment. 6. While the post-boost vehicle backs away, the RVs, decoys, and chaff are deployed (this may occur during ascent). 7. The RVs and chaff reenter the atmosphere at high speeds and are armed in flight. 8. The nuclear warheads detonate, either as air bursts or ground bursts.
The precise technical details are closely guarded military secrets, to hinder any development of enemy counter-measures.

Ok. So I was wondering how can Russia develop countermeasures to US MIRVs if it doesn't have detailed knowledge about the way MIRVs manoeuvre. As a Russian this is of concern to me.

Think of a MIRV as a glide bomb rather than a manouvering cruise missile.
