The 3 Future Superpowers

Europe

The mainland body of the European Union (France, Spain, Portugal,Germany) falls to sharia law as Radical Islamists use the strategy outlined in in the twenty year strategy spoken of by Anis Sorrosh to take over Europe by using it's laws against it. (Though the plan speaks of America it transitions well to Europe)

The Islamic Fundamentalist countries (I.F.C) territory will span the area of the old Roman Empire and Persia.

The I.F.C. will delcare open war on the United Kingdom, Israel, The United States/North American Union (N.A.U.) along with European countries that didn't fall like the Finland, Sweden, Iceland, Greenland,etc.

The U.K. Is the last "main" European country to fall as groups such as the B.N.P violently resist the "No go" zones that muslims use to impliment sharia law on a small scale currently rampant in France. They also violent resist the immigration of more Muslims and publicly persecute all Muslims leading to wide spread riots and strife.

The Vatican and other areas associated with "infidels" will be destroyed. Non-believers will be publicly executed as per sharia law (All non-radical Muslims).

The exports of petroleum to the rest of the world will cease. Sending the world economy into a freefall excluding the I.F.C.

North America

The United States becomes a socialist state in a manner similar to current European states and Canada. This is due to increased pressure from North American corperations for both "economic regions" to integrate as well as increased demand for socializing by those leaning politically left in America.

Further pressure from voters of central or south american dissent (in America) will push for integration of their respective countries into the union between the United States and Canada. This combined with pressure from corperations who opperate with a mentality of "what is good for the company/shareholders is good for the people" will pushing politicians into a corner and they will conceed.

The rampant corruption and poverty in central and south America will drive the population northward in search of jobs in the more stable countries of the United States and Canada.

With the influx of cheap labor the economies of the the U.S. and Canada will crumble as employers shed the more expensive employees in favor of the cheaper labor. The rampant loss of jobs would mimic the beginning of the current economic crisis with hundreds of thousands losing their jobs each month.

Additional factors such as Canada's dependency on the U.S (which currently buys 80% of all Canadian exports), Americas weakened state due to increasing debt, the continents dependency on middle eastern oil exports will cause the region of the United states to faulter and eventually crumble.
aa

Immediatly after the collapse the radical islamist in America will set up areas of Sharia law while Christian Fundamentalists set up similar areas governed by their doctrine. Utah will follow a similar path with Mormon Fundamentalism. The collective groups within America will begin to skirmish.

The "Canadian" government mobilizes troops to maintain peace within it's boarders, though with significant difficulty due to severe limitations on energy, manpower and thinly scattered populations.

Riots over food and other neccessities will paralyze major cities such as Toronto, Montreal and Vancouver. Outlying areas will be affected as people lose access to food and energy. Strife will break out as the Canadian military will not be able to maintaine order.

Hawaii may ceed from the Union and regain it's independence though little will come from that.

Asian Major

During the collapse of the United States and fall of the E.U. The Chinese will turn to Russiamin order to meet it's energy needs as well as becoming a trading partner in exchange for access to the plentiful natural gas and oil reserves in Russia.

China and Russia will intergrate and act as one (Asia Major Union). Russia will agree to this by fearing conflict over the energy reserves as Russia would not be in a position to repel China. North Korea joins the A.M.U.

At this time the A.M.U will acquire Taiwan, Japan, surrounding countries such as Laos, Cambodia, Thailand, Vietnam, Southern Korea, Phillipines, Malaysia and the former soviet block countries. Either through military actions, negotiations or other activities.

Areas bordering the I.F.C such as India, Ukraine, Lithuania, Belarus, Poland will become conflict zones where A.M.U. seeks to wrestle the land and resources from the I.F.C. While the I.F.C. attempts to repel the "infidel" invasion.

Israel

The state of Israel will lose it's American backing and will go on alert as the armies of several nations decend upon them. Israel will most likely put up a valiant fight but, the sheer volume of enemy soldiers will win the battle of atriction. Israel may launch it's nuclear weapons but, the end result will be moot.

The city of Jeruselum will fall and the city will be purged of all non-muslims.

Africa

The African Union will emerge before the economic turmoil as investers give the countries access to more infastructure but, internal conflicts of member states and between member states will prevent any significant.

The territory of the A.U. will span the entire continent of Africa minus the countries bordering the Mediterranean sea such as Egypt, Algeria, Libya which will belong to the I.F.C.

The African Union will never amount to anything significant as the I.F.C ceases to export oil sending these countries into chaos.

I.F.C countries will fail to immediately capitalize on this as their armies will be tied up fighting Israel and the A.M.U. Any armies sent into the body of Africa will be slowed considerably by terrain and local and regional warlords.

Ultimate outcome

The A.M.U will take on a campaign of genocide against the I.F.C doing everything short of nuking the rest of the planet. Providing the I.F.C military doesn't overpower the Chinese or a Nuclear weapon decapitates the A.M.U as a whole.
