The people who are "Suspected" to cause World War 3;North Korea - No, they're incapable of causing a large scale war, a lot of the contact between North Korea and any other country has been dismantled, North Korea is a very isolated country, and they won't be willing to expand their territories, unless they're given a golden opportunity, which pretty much means; Never.China - Nope, they get their own resources from trade through countries like Iran, and China is focusing on sustainable growth and renewable resources and energy.Russia - Never, they have plenty of natural gases to trade and use, they are also focusing on renewable energy too.America - Most likely, because they pissed off pretty much most of the world in the middle east and Asia.Europe - I don't see much imperialism going on, apart from the United Kingdom, but otherwise they're trolling the citizens that they have to pay higher taxes to "bail out" poor countries.Iran - Nope, they simply have the ability to create nuclear power, how fucking cute. America has over 300 nuclear missiles and are still producing more powerful ones, Iran are, rightfully afraid of the U.S. building military bases AROUND THEIR COUNTRY."Al-Qaeda" or "Tu'rrism" as W pronounces - Never, they have no capability to causing a large scale war, they never will, they rely on buying foreign weapons and foreign training.
Incapable of causing a large war. How cute. What caused WWl? The assassination of 1 man, and a lot of tension. What does the world have now? A lot of tension. Its really a matter of time, though its unlikely to happen very soon
China takes a "Hear no evil, see no evil" approach to war. Iran may be "friendly" with China, but is China going to risk its resources over a tiny piece of land such as that? Hell no.
