If you read the article, the range of the missile is 6000 miles.

Quote:
"Topol-Ms have been deployed in silos since 1998. The missiles have a range
of about 6,000 miles and reportedly can maneuver in ways that are difficult
to detect.
Earlier this year, a senior Defense Ministry official was quoted as telling
news agencies that Russia had developed a weapon that could make the United
States' proposed missile-defense system useless."

I don't think Afghanistan is the primary mission for the weapon.
