Next world war? Hardly. Even if the entire Middle East was united under one Muslim banner, they couldn't begin to challenge NATO. They would need some large and powerful non-Muslim allies, and that would seem to be counter to their aims.

I think there will always be war and it will get only worse. But I think World War is out of the question. With everyone armed with nukes, the opposing power will just nuke the other power to no end.

Personally, nope. Not in this way anyway. It'll have to be something... BIGGER. Yes, I do believe we are due for a world war, and yes I believe the middle east will be involved, but not the ones who ultimately caused it to happen (when it does). It'll be bigger nations (Germany in ww1/2, for example) like; Russia, China, USA, or even North Korea?

I think Russia could because their leader, Vladimir Putin, is still a capitalist hating, communist loving physco! And, with the trouble still going on in the Ukraine as of now (which western leaders believe is the work of Russia) could escalate even further!

China because, well, communism? Maybe? (bare in mind this isn't and "anti-communist rant). Or maybe someone will grow a backbone and speak up about Tibet? Maybe?

The USA (not hating on the US) could, once again, interfere in some conflict or escalating tensions and do what it normally does and drag European country's like France and Britain into it as well.

North Korea... What is there to say that we don't know? They're a "rouge state", if you will. They may be bluffing about their power, but they have China at the back for almost everything! Need I say more?

To end this, no and yes. This war in Iraq you speak of is not "on our door step" in fact, besides another Iraq war, nothing is. Not another world war. And yes, because we are humans, and history is mainly comprised of war, and, well, there's still allot of history to be made. The human race is still considered a "young" species and we have much to accomplish.
