"Over 70 countries have some kind of space program now.."
An impressive statistic--until you examine it more closely. How many of those 70 have actually launched anything into orbit (or elsewhere) from their own soil--and how many rely on other nations to do the launching for them?
I should have emphasized the "some kind" of space program because, you're right, countries like South Korea have had a space program, but one that totally relied on another country's (Russia) space program.
But... then again, the US falls into that category right now for manned spaceflight since the retirement of the space shuttle.
