Manhattan project

Imagine a man where it all began
A scientist pacing the floor
In each nation, always eager to explore
To build the best big stick
To turn the winning trick
But this was something more

The big bang took and shook the world
Shot down the rising sun
The end was begun, it would hit everyone
When the chain reaction was done
The big shots try to hold it back
Fools try to wish it away
The hopeful depend on a world without end
Whatever the hopeless may say

Imagine a place where it all began
They gathered from across the land
To work in the secrecy of the desert sand
All of the brightest boys
To play with the biggest toys
More than they bargained for
