In reailty a lot of polictical arguments happen when comparing weaponary and things like that. they like to show what toys they can hit other people with and say when they want to hit people. They dont understand the background of a conflict or the technical details or laws involed in some events. Im speaking of nationalistic people of certain nationalities. Logic doesn't seem to be a word in their volcaubray, but hard moderation is not the key to build a forum its membership
You also diversified the site way to early. start basic then work up. start with sections: recent events/Suggestions/Feedback/World Affairs. keep it simple to start off with and concentrate on core features like uptodate information. I know your approch was 'build it and they will come' but it doesn't seem to work so far, so make it simple for the masses.
Also some connection to a new source like yahoo news could also be good for it. We need a area where all the new news is concentrated in one area so when new people joing it would be easier for them to find. When a decent amount of regular people come to visit then start to diversify little by little by adding new features.

Advertisments?

Moderation should to kept to keep the swearing down but thats about it for moderation. polictics is not about good general peacful views but some line has to be drawn with logic and the insane
