ISIS is extremely well funded and armed
yes they just pulled off a bank heist but they were always well funded
The money is coming from sources in saudi arabia, qatar and even the CIA and Mossad
It is in the interests of the CIA and Mossad to destabilise the region. This then gives them the excsue to move conventional military forces back into the region to take control of it
This will help destroy the US as a viable state through military over reach
Military over reach will combine with the loss of the dollar as the global reserve currency, the de facto destruction of the US/Mexico border, approaching hyper inflation, unemplyment, stagnating wages and other factors which are creating the perfect storm for the US
The US is being destroyed from within
This will create civil unrest which the state will oppose VIOLENTLY using the chaos to crack down on political opponents (use peacful non cooperation not violent revolution!)
The removal of the US as a viable state will open the door to greater global integration moving the world closer to world government under a totalitarian dictatorial central government
