Help calm my wife down about the seoul trip please

hi all - I live in Japan, my wife is japanese and she has been looking at the recent news about the north and is freaking out a bit. We are set to go to seoul from thurs-sun this week but she is debating about going. I am telling her this is silly and nothing serious will happen, but that is seemingly not enough. How does everyone feel there at the moment? Apparently there are lots of jets flying over the city... But are any of you changing how you live?
