I'm now at the point that when I hear a weird sound as a plane flies overhead and wonder if it's a nuclear bomb, I think, "well at least it's finally over."

This is not a current-events-driven anxiety, I've done this all my life. And the formative years of that life were post-cold-war, there's little reason to have that intrusive thought. The only thing I can reasonably attribute my nuclear nightmares to is seeing Terminator 2 as a little kid.
