The chance that we are heading into WW3 is probably 75%+. The chance it will go nuclear is even higher. It will start in 2013 or 2014, unless the USA and NATO back away from sending troops into Syria.
War is imminent. The claim about Assad using chemical weapons is from the same Pentagon psycho's who tried to sell us the "Yellowcake Uranium" story, and Colin Powell's cartoon-like "Mobile Chemical Weapons Factories". These transparent lies, designed to demonize the next country in America's crosshairs, are a sure sign that another illegal war of aggression is commencing. But this war will be very different. It will become clear within days that America and Israel are not "winning" anything. Israel will be flattened. American aircraft carriers will sink. Every American base in the middle east will be a target for multiple munitions.
China and Russia have a mutual aide agreement in the S.C.O. Charter, and they do a lot of military exercises together. Russia has a naval facility in Syria, located at Tartus. Attacking Syria is the same as attacking Russia. Putin will not look the other way.
The US/NATO attack on Syria is a certainty at this point. Iran and Hezbollah have promised to defend Syria, and they will unleash more precision guided missiles on Israeli and US targets than anyone can imagine. China has made it clear to the USA and NATO that Iran is off limits. China depends on Iranian oil, and China will go to war before they allow America to steal Iran's oilfields.
Things will escalate very quickly once the cruise missiles start striking Syria. China and Russia will definitely back Syria and Iran. Once we have China, Russia, Iran and Syria fighting the USA, NATO and Israel that's WW3 right there.
Now here is the freaky part. There are a whole lot of Neo-Con's in the Pentagon who believe the USA and NATO can defeat Russia, China and their allies. They want WW3, and they believe they can "win" a full scale Defcon 1 nuclear war.
The reason they want this war, and the sooner the better, is this: The Pentagon and NATO represent bankrupt America and the bankrupt Euro nations. They know their economies are crumbling, at the same time that the BRIC economies are about to skyrocket. America will never again be the Economic Champion of the world. Those days are rapidly fading into a distant memory. Russia and China are both cooperating on unprecedented military modernization, expansion and exchanges of military technology. Roughly around 2020 these nations will be economically AND militarily superior to the NATO countries. This reality does not sit well with the Neo-Con decision makers in Washington and Brussels.
