Mon August 27: will being alike make the world more peaceful?

Greetings and salutations!

Last week we had an extensive and lively debate about whether people are more alike than they are different. Today I would like us to continue, but in a slightly different direction.

Consider this: war has been around since before recorded history began. For centuries, people have been killing each other. Now let us consider: do wars happen because people are alike? Or because they are different from each other?

In other words, do common interests make people LESS likely to go to war with each other?

And here's the kicker: I want each of of you to come up with at least three arguments, based on specific real world examples, on BOTH sides of this issue. That's a total of six arguments, consisting of at least one complete sentence each.

Time permitting, I would like to compile a list of the arguments, pro and con. Just like last time, it will go into a folder on Box.com, and be available for commenting by each of you at a later date.

cheers,
M. L

PS I will also need each of you to upload your six arguments as a file to your individual folders on box.com
