Russia has responded to  USA withdrawing from  arms treaty by announcing it has plans to build more missiles. News that  USA will exit  Intermediate Nuclear Forces Treaty (INFT) and Russia's response raised concerns about  new arms race. Moscow immediately said it would end its own involvement in  arms limitation treaty. In addition, Russian media stated that Russia's military would develop  "100 megaton nuclear doomsday device" in response to  USA pulling out of  treaty. The INFT was signed in 1987. It was  attempt to limit  number of missiles that were capable of hitting many European capitals. It banned both countries from using short- and medium-range missiles.
 media have written extensively about  new "super-missile". This is  unstoppable, undersea, 100-megaton nuclear warhead. Experts say it is so fast it can evade all current missile defense systems. They also say it is powerful enough to cause catastrophic devastation, such as creating 100-meter tsunami waves and enough radiation to wipe out life for  thousand kilometers. One Russian newspaper wrote: "One of  100 megaton nuclear warheads will sit off  US coast. Any US attack on Russia would be  suicidal misadventure." However,  paper omitted to mention  concept of M.A.D. - Mutually Assured Destruction. This scary scenario sees both countries wiping each other out.
