Canada better hope they don't miss us and hit them by mistake ! 
Hmm, I wonder if Russia would be upset if North Korea hit Alaska with a nuke ? Too close to for comfort for Putin ?
China has been busy building islands and trying to steal other people's islands so getting us distracted with North Korea should keep us busy worrying (not) about getting nuked by NK.
China has a much larger military then we do and they have millions more people in their country so it would be easy for them to run over us. 
Meanwhile, the Democrats are convinced that Russia hasTrump as their secret weapon here in the US. I have always thought we should worry more about China then Russia. About forty years ago I read a "novel" where the storyline is about China taking over the United States after invading.
