Russia working on new weapons

Russia is developing a new intercontinental ballistic missile mounted on a railway car. Government officials say their stated goal is to counterbalance U.S. weapons in the pipeline. Col. Gen. Sergei Karakayev, the chief of the military's Strategic Missile Forces, told Russian news agencies that the new weapon will be much easier to camouflage than its predecessor. The Soviet-designed railway missiles were dismantled in 2005. So what does this mean for the Cold War? Many say it never ended.
