I could have guessed. Start with the current leadership and their support of Syrian rebels. It is no mystery anymore that the American leadership supports Islamic terrorism and destroying governments. It’s the same thing the Democrats did in Kosovo. Support the underdog, break up the nation, loot it for spoils. These are not the actions of politicians but of criminals.
I also think it’s no coincidence that this all broke out right now. I think Al Qaeda was very emboldened by Obama’s surrender to the Taliban in the juicy deal the Taliban got.
They know that he has no wish to oppose them, and that they are safe from the US.
