How the Atomic Bomb saved the world- And may do so again

The A-Bomb was in devolopment in the 40's because our intelligence told us that Hitler had many scientist working on one of their own. It was the begining of what we would soon call the arms race. But after Germany surrenderd, the 2 Billion dollar project was nearing completion. But at this time, it seemed as if the project would never get a real field test. But fate has a funny way of seeing things through.
The turning point in the projects fate may have been when Truman took office. After the surrnder of Germany, plans were being put in place for a full scale land invasion of Japan. But there was one problem. The Japanese suspected this would happen. So in preperation for this invasion, they began traning ordinary citizens to combat the American forces. Considering the great losses in troops in the south pacific theater, truman knew that the invasion of Japan would result in another D-Day, or possibly worse.
Truman did not want to face the great loss of American troops, when there was alredy a weapon that could strike fear in even the hardest of hearts. So he made the decision to use the Atomic Bomb.
If you take the history of WWII, and really look at it, you will see that we are facing a very similar enemy today. Wiling to sacrifice themselves for what they believe is the greater good. And maybe, only drastic actions will make them reconsider the path they walk in life. Truman used the bomb to save American lives. If push comes to shove in the War on Terror, will our politicians in Washington have the strength to do the same? In our current political climate, I would say no, but I hope I am wrong.
