Waco Texas explosion

The tragedy resulting from the explosion of the fertiliser factory exposes the dangers of large explosions.
Buildings were destroyed at a considerable distance from the factory. The blast could be heard 45 miles away and the power of the explosion registered 2.1 on the Richter scale; it created a minor earthquake. Had the explosion happened in the middle of a city hundreds if not thousands of people could have died.

But this explosion is nothing compared to a thermonuclear one. If an H Bomb exploded in NewYork, Moscow or London millions would die. It makes me wonder why we had to invent such weapons in the first place.

A stable and democratic nation was the first to use the less powerful A bombs with the result that hundreds of thousands of civilians died. If Adolf Hitler  had developed the A bomb first there is no doubt in my mind that he would have used them without mercy to obliterate Russian and British cities. We must hope that an unstable nation is never able to deploy such weapons. But I fear that sometime in the future this could happen.

We cannot reverse history and "un-invent" nuclear weapons. The Western powers did little to stop Israel from obtaining nuclear weapons and the Eastern powers have also been unable to restrain North Korea. This could lead to the possibility of another arm race where Iran feels no moral restraint to creating a nuclear weapon. Japan also has the the ability to quickly develop a nuclear weapon if it chose to do so.

I doubt that the human species has the sense to impose nuclear disarmament on itself so I fear it is only a matter of time before nuclear weapons are used again.
