> Germany could be and would be the top scientific and technological nation of the XX century (space research, computers, etc etc) if they had not gone mad.

Twice.

And you know this how? Developing computer and space industries takes a lot of resources, which Germany would not have had.

Do you mean natural resources and so? They could have been bought.

I mean money and ppl. The computer industry in US was a product of enormous investments during WW2, A/H bombs projects, moon missions. Countries like USSR, UK, France, China were left far behind and had to copy most of US technology. German advances before WW2 were to a big degree product of US investments. Could it pay back and invest in basic science, while having no colonies and probably no access to most of world market?

Suppose Germany had spend the money used to wage WWI and WWII for science instead?

By the way, Britain's computer industry was on par with the American one just after the war.
