That's pretty much my take as well. GWB has always been a one-world no-borders immigration nut, and he never hid that. He was no ideal choice but he was the choice the voters were given - that election was a perfect distillation of just how far the globalist establishment had succeeded in arranging a national election such that only its candidates were available. We were nearly given a similar choice in Hillary vs. Jeb. Heads I win, tails you lose.
I would not think that Dubya has a great deal of credibility when it comes to masterly intelligence analysis, though. That dog not only didn't hunt, it laid down on the porch, started wheezing, and died.
Pretty sure dad(ghwb) got to signing us into Agenda 21 if memory serves.
