What do you think is going to possibly happen , is this a sign of WW3 that we have been getting for a long time? As a politics major , there are so many questions , not many answers

Hard to say. For WW3 there would need to be other countries that would side with NK. Right now their only ally is China and the relationship is pretty strained.

China itself is a strong nation , but yes that's right too, other countries will need to be involved . If it ever happens , I hope all the countries that US went against, do not turn against us
