If we keep building nuclear weapons, this will keep happening - and eventually, one day we'll pull them out and use them in earnest.

I cried with relief when Obama was elected and yet one of his last acts as President was to authorize a trillion dollars in new nuclear weapons.

Each nuclear weapon built, even if it is never used, is a crime against humanity. And nuclear weapons aren't even the greatest threat to our civilization.

I just don't think this is going to end well.
