Well, it's really a question of priorities. The United States could have competed with the Soviet Union in terms of outer space, but the USA has always been pushing the envelope in terms of nuclear power.
Although the first Commerical Fusion Plant only came online in 2003, it followed decades of investments, enhancements and progress in terms of understanding the true implications of splitting the atom.
Compare a sterling silver safety rating and half of our domestic power drawn from these plants with tragedies like the Beloyarsk Nuclear Disaster (and the subsequent evacuation of Sverdlovsk); the United States might not be winning in space, but we're world leaders in energy.
So the Russians made it to the moon, big whoop! We have the world's only Thorium Reactors, the first high-efficiency Nuclear Plants, and the first and second Nuclear Fusion Plant. I mean, we could be held hostage to $5 a gallon gasoline and get to the moon, or we can keep our national High Speed Rail system, our highly advanced power grid and our insulation from insane madmen in the Middle East.
We didn't get our flag on a pile of Cheese, instead, we got The Power. I think we had a worthy national focus.
