They are actively seeking a planetary wide two class society. Having attacks occur on the US helps them bring this about. Not "all" of them but enough of them are involved. It's a loose goal, and I wouldn't maintain there is any over-all one single group or faction, but there's enough of them with similar interests to have incidents like this, the first wtc attack, the okc attack , etc, to happen. All they have to do is step back, let it happen, then voila, they kill several birds with one stone.
Look at the results-perpetual war for perpetual profits, increasing centralised big brother style government, not only in this nation but all over. Look at how chinas two class techno society is constantly rewarded, and who is putting their money and interests into expanding them, both politically and business-wise. And they have millions cheering them on. Look at who is profiting from these actions, and it goes way beyond some mad jihader puppets.
The deal is, it's way too scary for most people to even contemplate the depths that they have been lied to and faked out over the years, even the simple consideration of it gets dismissed out of hand, despite little clues like this one here.
This article is just another in a huge and overlapping stream of incidents that would support this view. It's not just 'bungling" or incompetence, these actions are taken with cold blooded intent, for exact goals as I outlined above. And here's another hint, it's all just not 'the democrats" doing it, or even just "mad jihaders" no matter how much most people insist on stopping at that exact point with their looking. We got globalist traitors in very high places, and so do other nations, their only loyalty is to themselves and to establishing this global despotic governmental structure loosely based on the surface around "national governments" but in reality based on massive financial and social control. It's really just a normal historically similar series of crimes, taken to astoundingingly high and sophisticated levels. Who profits? Always ask that with everything that happens is a good rule of thumb I think.
