As for your personal safety, I would not worry too much. If worst come to worst the city you live in will only become a target after all the US missile silos have been destroyed and that will require a great many bombs. There probably wont be a bomb leftover to throw at you.
I have recommended to Trump in one of the surveys that he sends to we old time Republicans, to ignore the North Koreans like we have for 60+ years. However, if they attack South Korea, he can drop Kias on them.
Russia invaded my home nation Ukraine, and I was in France, so I became a refugee. Friends from Italy, Japan and the USA helped me. i do not want to see more wars anywhere, but wishes do not come true, except in children's fairy tales. I fear to go to France, because of the Muslim war, but Italy just closed its borders and Japan did some time ago. Trump is trying to close the USA to the terrorists, but liberals will not cooperate. I think Korea would be crazy to start a war, but its leader is insane. This is a tense time in many ways.
I don't know why people keep saying Trump is trying to start a war with N Korea. They are the ones who are pushing the issue. We have tried everything to avoid an attack on them. I guess we are just supposed to sit back and take whatever they do in stride, even if it means them dropping a bomb on Guam or Hawaii. I guess you would be OK with Hawaii being bombed?
