We could have gotten nuclear tech without the will to kill people. There are smart scientists outside of the military, and a need for power plants. Which everybody agree would have been built with safer tech without the need for the bomb.
Now the problem is never the tech, as usual. It's that the society we are living is not constructed in a way that can prevent the tech from being abused.
We are talking about a country that attacked Irak while lying out the WMD and against the vote of the majority of the world, killing countless people for no proven result and living a country still in ruin decades after that.
I'm not really trusting with the governments we have.
