The Atomic Bomb

The bomb cost about $2 billion spent on its development, it killed 100,000 people in Tokyo.
The Atomic bombing was an unwise idea. I'm pretty sure there are so many other ways to solve the problems. The atomic bomb killed thousands and thousands of people, it costs billions of money, it wasted human resources, it destroyed countries and land, it polluted the air and it produces poison gases which make people ill and die.

I think they should just deal with the problems, sign a contract or treaty, and just do what it said, that would've solve more problems, and it won't hurts that many people.
