This is an excellent book. It details a subset of the larger Vulcan group, neocons with a root in the Nixon era. It is best when pointing out the plans that were constructed in the early 90’s, plans in which it is made clear that the twin goals of this crew were to ensure continued access to mideast oil, not so much to ensure cheap supplies, but to ensure secure supplies, and to prevent hostile powers from controlling that resource. The other goal was to spread liberal democracy to the middle east. The notion was that extremism was an outgrowth of the autocratic regimes of the area and installing democracy would remove the source of that extremism. In a sense it was an idealistic notion.
There is also much here about the personal relationships of the various players. It is clear that Colin Powell was never a true insider although he did not exactly stand in the way. His gripe was in form, not substance.
The Vulcan orientation was foreign policy. Domestic policy simply did not appear on their radar. Thus they are not factors in the mad tax-cutting of the Bush administration. Much detail here. It clarifies a fair bit. A must read
