You could use that excuse for almost anything morally repugnant.
Someone will have it.
So how do you best mitigate the bad effects it can have? Do you let an entity which does not align with your interests have it? Or do you maintain it and work to iteratively improve your exercise of it?
The effect of wishing away power instead of grappling with it and bending it to justice is one of the central reason why many revolutions and movements have failed.
I suppose that means, I could do my part to keep it that way, by investing in US defense contractors. (Have been looking for investment opportunities.) Something to think about.
If there is another triggering event like 9/11 (which kept the defense industry alive), it will be a real surprise to see the US muster a response the way they did in the past.
Consider, for example, nuclear weapons. I think it's generally agreed these days that nuking Hiroshima and Nagasaki was unnecessary at best, a war crime at worst - but I don't really see that a better world would have resulted from the USSR or Germany being the first to obtain nukes.
