I have quite a lot of people, who think that science, that is not immediately useful for industry/businesses is not something that we should be giving any money to.
Well, now I had found the answer that I can give it to them, when I hear about it again. The letter that Ernst Stuhlinger write gives probably a lot better description, than I am capable of producing.
The copy of the letter can be found here: Why Explore Space.
When you are reading it, there is going to be a part about international cooperation. Keep in mind, that the mentioned Apollo 13 mission took place in 1970. At that time, the relationship between US and Russia were a lot different, then they are now.
