"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.
Als o in that link: The Atlas 5, one of two rockets used primarily for U.S. military missions, is powered by another Energomash engine, the RD-180.
Moscow threatened to cut off exports of the RD-180 for U.S. military missions in response to U.S. trade sanctions spurred by Russia’s annexation of Ukraine’s Crimea peninsula. So far, however, business has continued uninterrupted, says United Launch Alliance, a Boeing and Lockheed Martin partnership that manufactures and flies the Atlas rocket.
