In that case, next time we speak about the real world, use your encyclopedic historical knowledge and give as examples events that happened in the real world, and not in a fictional utopic universe that sprang from the imagination of a few scenarists and writers.
Ok, Proto you do realize that you are contradicting yourself here, first you're mad at the others for using real world examples, and now you are telling to use them. It is a little confusing.
As for the real world vs Star Trek, there is a very major factor that you are not aknowledging, ST was created in the real world, and many of the races, and events are based on stuff from the real world. So looking at how things happened in the real world, really is the best way to look at how things might turn out in Star Trek.
You're also making alot of assumptions based on very little evidence. Just because we saw a race act agressively in it's one or two appearances doesn't mean that that is the only way they act.
