Can you provide one shred of tangible evidence that leads you to believe that's the case?
It's happened before, it's not unprecedented. The governments of the world have time and time again allowed ,or sometimes downright created, attacks in order to drag their country to war;please refer to the Gulf Of Tonkin. Just look at this video from this influential lobbyist.
Once you understand the state of mind that the elites have, you would understand that they are willing to do anything to meet their objectives. I said this before in another thread, the government are capable of anything.
If the NSA and the French secret service are capable of monitoring all our activities, then why were they not apprehended? Are we giving away our privacy for no reason if they can't even stop terrorist attacks? And why were none of the alleged terrorists taken alive? Why were they all killed?
It isn't a huge leap of faith to assume that the powers that be benefit from this attack and therefore allowed it to happen or even helped it happen considering the political climate of the world right now. They are effectively killing two birds with one stone; getting troops into Syria to counter Russia, fighting "Isis" and limiting the refugee crisis by shutting down all borders.
Also France are part of NATO, so since shyt has hit the fan the U.S. And the UK and the rest of Europe can finally legitimately put troops into Syria to fight Assad.
