Winston, I am going to explain something to you with the understanding that there is less than a 2% chance that you will be able process what I post.
In any war there are many conditions that can lead to war. There are many hypothesized reasons or causes for wars to begin. Some of theses causes are valid justifications for war but some are NOT valid justifications.
Stay with me Winston, this is the important part. There are some real bad people such as Hitler and Putin who DID NOT have valid reasons to start wars killing hundreds of thousands of INNOCENT people.
Any discussion of these wars should start with a condemnation of these psychopaths. Never try to whitewash these horrid crimes against humanity by putting blame elsewhere.
