The most frightening aspect of the present threatening situation, which was not relevant before the start of the two world wars, is that all the three involved countries have the biggest stocks of nuclear weapons. (countercurrents.org)
In addition six other countries also have nuclear weapons. (countercurrents.org)
Eric Schlosser, a widely acclaimed writer on nuclear weapons, has spoken at length to top officials and commanders at various stages of planning and control of nuclear weapons. (countercurrents.org)
In addition he has close contacts with peace movements struggling for a world free from nuclear weapons. (countercurrents.org)
He has written that these very different persons all share a very strong and sincere desire to avoid actual use of nuclear weapons. (countercurrents.org)
The reason why both these sections share this strong belief is that both groups are well-informed about what actual use of nuclear weapons means. (countercurrents.org)
Schlosser has written, "The latest studies suggest that a relatively small nuclear exchange (relative to the total number of nuclear weapons that exist in world) would have long-term effects across the globe. (countercurrents.org)
While this has been written in the context of the use of 100 nuclear weapons of roughly the destructiveness of Hiroshima weapon, the total number of nuclear weapons in the world is over 13,000 and the destructive capacity of many such weapons is much higher than the bomb used on the people of Hiroshima. (countercurrents.org)
It is clear that apart from killing millions of people immediately, exchange of nuclear weapons can lead to unprecedented environmental catastrophe which can kill an even larger number of people while also destroying other life-forms like never before. (countercurrents.org)
Some strategists have argued that there can be a less catastrophic role for nuclear weapons in the form of tactical nuclear weapons. (countercurrents.org)
A nuclear war started with tactical weapons can easily spill into a full-blown nuclear war if the opposing side also has nuclear weapons. (countercurrents.org)
Secondly, use of even tactical nuclear weapons can be very destructive, even for the using country! (countercurrents.org)
