Let's talk about the Hiroshima bombing of the 6th August of 1945.
I want to attract your attention about this major historic event because I went in this city last December, and I have visited the Hisroshima Peace Memorial Museum with friends.
At 8:15 am on August 6, 1945, the city of Hiroshima fell victim to the world's first atomic bombing. The entire city was virtually leveled, and thousands upon thousands of lives were lost. Many of those who managed to survive suffered irreparable physical and psychological damages and still suffer of the effects today.

The United States wanted to force Japan's surrender as quickly as possible to minimize further American casualties, and also wanted to use the Atomic bomb before the Soviet Union to establish its dominance after the war and to measure the effects of this weapon.

After a few months of reflexions, US Army chose Hiroshima because it was one of the only Japanese cities to remain intact, and the topography of the city was well suited to observe the destructive power of the A-Bomb. In addition, there was a great concentration of troops and military facilities in the hearth of Hiroshima.

In this August morning, all the inabitants were preparing to have a standard day, but at 8:15 am, with a blinding flash, the bomb detonated approximately five hundred eighty meters of the city center. The heat rays and blast burned and crushed nearly all buildings within two kilometers of the hypocenter taking 140 000 of lives.
It's necessary to understand that the Nuclear weapon have three majors effects:

• Damages by radiation: Very caracteristic of an atomic weapon, the radiations inflicts severe injuries to the human body. In this case, about one kilometer above the hypocenter, people were so exposed to radiations that they died in a few days. A wide range of symptoms affects the people, its includes bleeding, loss of hair, severe fatigue. Aftereffects begans to appear about two years later and includes leukemia and various cancers. It continue to plague survivors to this day.

• Damage by heat rays: At the instant of detonation, the temperature at the center exceeded one million of degrees celsius, generating an enormous fireball. One second after detonation, it had extended to its maximum diameter of two hundred thousands meters and temperature on the surface reached 5000°C. No need to tell you how damaging this temperature can be.

• Damage by the blast: At the moment of explosion, an extremely high pressure is created. At 500 meters of the hypocenter, the blast pressure 19 tons per square meters.

With this speech I want to attract your attention to the extremely high level of cruelty this weapon is able to inflict to innocent population. Virtually, the using of atomic weapon is going against all the international treaties, including the Geneve convention.

But in France today for example, we have about 350 warheads, and in the world, up to 20 000 warheads remain, and about 8 countries are known to have or trying to have atomic weapon.

Only the quarter of this amount of munitions is enough to erase all kind of live of the surface of our planet.

I think that in a country like France, which have been the fourth to have the A-bomb, we widely underestimate the physical and psychological effects this weapon can have during decades and decades to innocent civil population. Another question is the ethic at war time, when we see the cowardice of using such a distant and widely-damaging weapon.

Nowadays, Hiroshima is one of the world's most peacefull cities, with a special atmosphear and a very special state of mind.
