What? I can name 4 superpowers in the past century alone that have caused more death than us: the Empire of Japan, the Soviet Union, Nazi Germany, and Maoist China. What millions upon millions of people has the United States been directly responsible for killing? Actualy, that's a good point, I wasn't thinking...I meant to say prior to other modern superpower, the USSR, but I screwed up. I was thinking from the viewpoint of sustained empires throughout history, a la the Persian, British, Spanish or Roman. The other two are where you run into with what I find too subjective about this. Most historians wouldn't count Imperial Japan or Nazi Germany as comparable superpowers or even empires to what we're talking about with post-WW2 America, USSR, or even other superpowers/empires throughout history. Of course, you could also argue that what we generally believe is a "superpower" didn't exist prior to 1945. If that's the case, you could even further argue that China was by no means a superpower during Mao's time and has only relatively recently reached the point where it could even be considered a superpower. That leaves the only models for superpower-dom as the USSR and the USA, in which case my more deaths point falls apart. But at the same time, is being more benign than the Soviets any great feat? The subjective part I throw out there with the deaths is how can you even accurately judge it? If our money or weapons are involved in conflict, aren't we arguably responsible for the deaths? No, you're not gonna trump Stalin's numbers, not even close, but again, does that really make us truly "benign?" I'd still argue we have easily been responsible to varying degrees for millions of deaths over the last 60+ years. Is that truly benign? We've shown no qualms with pushing other nations into conflict, or choosing sides in them and supplyin them with weapons, resources money or even military aid/advising. We've entered more international, large scale armed conflicts ourselves than any other nation or superpower since WW2. Is that really benign? Do we do a ton of good? Of course. Are we benign? In my opinion, not even close.
