I don't think that Americans can win a war with North Korea. North Korea is much stronger than Americans. Trump was made some serious mistakes and I hope for his own good, doesn't do more.
I hope for your own good that you don't honestly believe NK is a more militarily powerful nation than the US. Even so, trust me, no one in their right mind wants a nuclear war. Don't let yourselves get caught up in the media sensationalism that there is going to be a nuclear war between the US and any other nation in the world any time soon. The media is only doing what it does best... fear-mongering. And Kim is doing what Kim does best... making threats he has no intentions of backing up. The fat little dictator is full of hot air.
