Vladimir Putin is assembling a terrifying set of superweapons that may bring nations to their knees at the simple push of a button.Deep inside Russia's military machine, the tyrant is quietly assembling an arsenal designed not to win a war in Europe, but to decimate entire nations. His scientists are racing ahead with a terrifying array of nuclear systems that sound closer to doomsday fiction than modern military reality.They are building a suite of super weapons designed to frighten the world into submission - but these are not just bombs and missiles. Putin's arsenal of superweapons include nuclear-powered underwater drones, reactor-driven cruise missiles, hypersonic attack vehicles and even suspected space-based capabilities that American officials warn could, in the most extreme scenario, blind satellites and plunge whole societies into darkness. If Kremlin commanders are to be believed about their 'Poseidon' doomsday torpedo, a detonation would hurl a gigantic wall of irradiated seawater across coastal cities and naval bases in the West.For decades, Washington and Moscow relied on mutual deterrence and painstaking arms control treaties to ensure nobody crossed the line. Many treaties have been pushed aside or are totally dead, and military communication channels are strained. Russia is at war in Europe and has repeatedly rattled the nuclear sabre. And each time the Kremlin announces progress on one of its so-called invincible weapons, military officials and diplomats in the West exchange looks that say it plainly: the world is now closer to nuclear peril than at any point since 1962. Tuesday's announcement that Russia has successfully tested its new Satan-2 intercontinental ballistic missile has pushed the West further towards the precipice of nuclear doom. To make matters worse, Putin said that Russia planned to put the Satan-2, also known as Sarmat, on combat duty by the end of this year. Moscow claims that these machines aren't just being stored away for future use, but are being actively tested for use in the near-future.
