If you look at the news you see glimpses of some of the "discourse" on foreign soils. And some look at this in shock and awe.
During the times of the Greeks, Romans and others war was a constant. In one of the missing/hidden books of the Apocrypha are several chapters relating to these wars Maccabees were the champion army that kept the Greeks who thought they were superior to all in check. It seems that there is always a bully in war. The basic reason for fighting is someone wants to take something from the other. So wars have always been and it looks like they will always be until the end of time. The unfortunate part is that a lot of people die in war. We will have to live with that. We can pray for those engaging and those who are victims.
Matthew 24:6-7 And you will hear of wars and rumors of wars. See that you are not
alarmed, for this must take place, but the end is not yet. For nation
will rise against nation, and kingdom against kingdom, and there will be
famines and earthquakes in various places.
