So far, the world has managed to avoid a nuclear war, although during the 1962 Cuban missile crisis it came distressingly close. There have also been several scary incidents when U.S. and Soviet forces went to full alert because of faulty radar images or a test tape that someone thought was real. While the military downplays these events, former Secretary of Defense William Perry argues that it is pure luck that we have avoided a nuclear exchange, and that the possibility of nuclear war is greater today than it was at the height of the Cold War.
In part, this is because of a technology gap between the U.S. and Russia.
In January 1995, Russian early warning radar on the Kola Peninsula picked up a rocket launch from a Norwegian island that looked as if it was targeting Russia. In fact, the rocket was headed toward the North Pole, but Russian radar tagged it as a Trident II missile coming in from the North Atlantic. The scenario was plausible. While some first strike attacks envision launching a massive number of missiles, others call for detonating a large warhead over a target at about 800 miles altitude. The massive pulse of electro-magnetic radiation that such an explosion generates would blind or cripple radar systems over a broad area. That would be followed with a first strike.
At the time, calmer heads prevailed,, and the Russians called off their alert, but for a few minutes the doomsday clock moved very close to midnight.
According to the Bulletin of Atomic Scientists, the 1995 crisis suggests that Russia does not have "a reliable and working global space-based satellite early warning system." Instead, Moscow has focused on building ground-based systems that give the Russians less warning time than satellite-based ones do. What that means is that while the U.S. would have about 30 minutes warning time to investigate whether an attack was really taking place, the Russians would have 15 minutes or less.
That, according to the magazine, would likely mean that "Russian leadership would have little choice but to pre-delegate nuclear launch authority to lower levels of command," hardly a situation that would be in the national security interests of either country.
Or, for that matter, the world.
A recent study found that a nuclear war between India and Pakistan using Hiroshima-sized weapons would generate a nuclear winter that would make it impossible to grow wheat in Russia and Canada and cut the Asian Monsoon's rainfall by 10 percent. The result would be up to 100 million deaths by starvation. Imagine what the outcome would be if the weapons were the size used by Russia, China or the U.S.
