The most important ignored story of 2015 is Russia and China setting up their own economic alliance incorporating a whole host of other entwined organizations and countries such as India, Venezuela, Iran. The last two nations also seeking protection from US imperialism.
Russia and China will also be setting up their own version of the World Bank, the NDB, that will use the Chinese renimbi so it will be essentially a separate economic system in competition with US banker hegemony.
This will also provide a counterpoint to a unipolar world. If the Iran deal falls through either because of Republican intransigence in the legislative process or the election of a less friendly presidential administration in 2016 be they Republican neo-conservative or a neo-liberal like Hillary Clinton, a Russia/China alliance will protect them from America belligerence.
Behind this belligerence is Zionism and Israel. This new alliance will of course be less friendly with Israel, in fact will be diametrical ly opposed to their goals of domination and control of the Middle East. China recently announced it would not allow its workers to work on projects within the occupied territories particularly new settlements.
A force, an alliance, in the world more on the side of working people, on the side of countries to pick their own leaders without outside interference, is desperately needed. This agreement is banking and militarial (All the participating countries will be part of a joint military organization like NATO) but also transportation - High speed rail connecting the countries of Eurasia.
And last but definitely not least will develop political power and clout through access to natural resources that member states share for example Iran's oil and Russia's natural gas.
A unipolar world where the dominating force is predatory capitalism hiding behind terms like austerity which is really just cutting programs for poor people in order to cut taxes for rich people coupled with the tendency of the USA to invade other countries it does not like or agree with or undermining democratically elected governments (like those in the Ukraine and Honduras) with coups - This is why the world needs this new alliance. Hurray for Russia and China!
