North Korea aggresion(short post)

I assume most of you have heard the news about North Korea launching a test missile over Japan now, but if you haven't here is the news.
This morning, North Korea launched another test missile into the air, right over Japan landing in the oceans. The Japanese alarms sounded as everyone looked into the sky and saw blazing missile heading right toward them. I can't imagine what they would have thought at the time.
My opinion is that North Korea is testing their power and authority. They're trying to provoke us into making the first move so that they'll be able to fight back as "defense". President Donald Trump has also stated that the US is ready for war and will be prepared to back up the allies. War may be coming up in the future, but North Korean military could be stronger than we think. One thing is for sure.
