Gosh, so many uninformed and depressing posts in this thread. I feel obliged to debunk!
1.Nuclear- God, the amount of good this has done. Think of everything that involves radiation! That's Microwaves, radiography, radiotherapy, a whole shitload of knowledge about space, remote controls, more advanced heating and lighting. Nuclear power. Nuclear Fusion on Earth by 2025 (I think that was the prediction).
And we get Nuclear bombs on the side. So what? It can easily be argued that they have stopped wars and ushered in a new age of piece among those who have them.
2.Religion- Well, there have been wars in the name of Religion, but a lot of our early scientific discoveries were made by monks and other devout people. They also made large (Sometimes false) contributions to medicine and education. Literacy and the printing press can both be traced back to religion. As can communism.
3.Communism- What is everyone's problem with communism? Sure, it hasn't worked yet, but it hasn't been genuinely implemented yet, has it? Jeez, the amount of hate on it you'd think it was some kind of disease. Stop following the crowd and stop listening to the propaganda.
