How Powerful Are Nuclear Weapons Too Powerful?

I believe that nuclear weapons are too powerful. The use of nuclear weapons can result in a massive amount of lost lives. Both military and innocent civilians. There are also long lasting effects of nuclear weapons. From the bombing of hiroshima and it was found that half a century later people still suffer from the after effects like cancer and birth defects. Radioactive particles from the explosion can also contaminate the air, soil, water and the food supply. It can also be carried by wind currents to different locations causing environmental damage to places far from the actually drop of the bomb. Nuclear weapons can also cause massive amounts of damage to a country's infrastructure and cause economic issues that can affect other states. However, although they are powerful and have the potential to deal large amounts of damage. I think nothing should be done about them.

A state is less likely to go to war against a state with nuclear weapons regardless of whether they have them themselves or not. A nuclear war could result in massive amounts of lives lost, economic destruction for both countries, and the cost for manufacturing nuclear weapons is high. As a result of this countries are more likely to consider all options before going to war. Nuclear weapons also help prevent wars with smaller, weaker countries that are allied with states that possess nuclear weapons. States would be afraid of attacking the allied states due to fear of the nuclear states retaliating. Due to the high cost of nuclear weapons, it also makes it easier for states to talk diplomatically to work this out, since no one wants to get into a conflict that can end with the use of nuclear weapons. This makes it more likely that both nations would first resort to negotiating to reach an agreement or compromise. To insure that massive destruction is avoided. Which helps guarantee peace for as long as
