NK are going to do another test again any day. It depends on what they do and how the US reacts. It is very strange though there doesn't seem to be any military build up in the area or pulling out of US citizens etc. Trump seems rogue on his Tweets and they seem to be the biggest threat along with KJUs rhetoric. The military seem to want to deter and contain although the situation is prime for miscalculation.
I am not certain of the facts, but this caught my eye: since the United States was founded in 1776, she has been at war during 214 out of her 235 calendar years of existence. In other words, there were only 21 calendar years in which the U.S. did not wage any wars.
I have not yet looked at North Korea & Iran's record, but doubt it is as bad.
Not sure what the relevance is to be honest. The amount of time Britain spent 'at war' prior to WW2 was pretty awful, but that didn't mean we were wrong to go to war with Nazi Germany.
