How will they distinguish between refugees, migrants or terrorists?

This year is going to be very unpredictable. The war in the middle east goes on, a previously unheard of virus, called the Zika virus, is causing microcephaly in babies in Brazil, the global economy could fall into a recession, China's growth is slowing down and the US is in the middle of its election jamboree. But it is Europe, thinks a professor, that is going to decide the geopolitics of the world. The many challenges facing Europe are recognised by the President of the European Parliament who thinks that nations could yet unite to solve the problems. " It is time for Europe's leaders to break the decades old habit of pursuing half-baked projects that blunt the symptoms of crises, and to implement real reforms that address root causes," he writes. " If Europe's leaders are to inspire their people to build a shared future, they must demonstrate an understanding of what the future has in store - and how to make the most of it. They should start by changing attitudes and committing to working together to face present and future crises head-on." Pious words. But just when we thought that a united Europe will follow common policies he recoils." My call for a renewed commitment to the EU does not stem from some federalist mantra," he hastens to correct himself. Exactly. The European Union is an assortment of 28 nations, each with its own elected government and different economies but with no control over monetary policy, which is set by the European Central Bank. That has created a north-south divide where the rich north feels that the south must become more competitive, while the poor south feels that the north is being vindictive. Perhaps, the migrant crisis will create a crisis that will decide whether the EU breaks up behind barbed wire fences or unites in a federal Europe where policies are common to all. The EU has blamed Greece for allowing migrants to come into Europe to which a spokeswoman for the Greek government responded," This tactic of diverting responsibility is not an effective response to a problem of historic dimensions." The Syriza government in Greece may still be smarting from the severe austerity imposed on them by the Troika and presumably see no reason why they should be spending scarce money on migrants. Apparently, Germany is unable to locate 600,000 migrants out of 1.1 million that it has admitted. Many have multiple identities and cannot be tracked by official agencies. Denmark has passed a law to confiscate valuables from migrants, which has been criticised by the United Nations. Sweden is to expel 80,000 refugees, but where to? In Finland some are adopting the Ku Klux Klan. Further terrorist attacks are certain in Europe's cities. How long before we see all out war?
