I disagree. Firstly, whilst the ends do not justify the means, this was an incredible technological and cultural achievement. Humanity's first, faltering step out of the cradle.

Secondly, two great warrior tribes holding enough weaponry to kill every human on the planet many, many times over hold guns to each other's heads... and then divert competition from violence into technological achievement. The message no longer just "I'm best because I'm stronger" but now also smarter, more technologically advanced. Means of competition that does actually give the world a brighter future, rather than just ending it for the other tribe.
