If all the countries who've gone to the Middle East to fight the Assad regime and ISIS had done their job properly from the beginning, this forced exodus would not have occurred. They would have done their best to protect citizens 'temporarily' locating them to the north, where food and shelter could have made it through, then they could have had thousands of soldiers surrounded ISIS and taken them out, swiftly and effectively. How many soldiers are we talking about when the following countries joined the coalition; France, England, Germany, Canada, the USA, Morocco, Italy, Australia, etc The Generals knew approximately how many ISIS soldiers they were dealing with; so with all these countries involved, they could have easily quadrupled the numbers of ISIS. Instead they decided to send jets!! And once done, they could have taken care of Boko Haram.
