The similarities of the PNAC America to the German 3rd Reich that *I have personally noticed* are few yet profoundly importent.

Here are 8 off the top of my head:

The national unification over the destruction of a famous building.

The abundance of private armies, in Germany it was the SA otherwise known as the brown shirts under the direction of Roeme. They were not part of the official German army but at one point outnumbered the army. THe US has over 132 private military entities in Iraq.
SOme you know like KBR Halliurton CACI TITAN Blackwater and some you kn't know such as Custer Battles who was sued by an FBI agent in US court for stealing $7 million in goverment money by overbilling. IT was overturned since private armies in Iraq are not bound by US laws but by the Iraqi intermim goverment ---yet Condi Rice claims that Blackwater can not be charged by the Iraqi goverment either...
but let me not digress into the full range of war profiteering.

The suspension of various parts of the Constituion as well as the Constituion as a whole.

The engineering of elections by tricks murder and propoganda.

The politics of Invasion.

The scape goating of certain segments of the population. In the US it is more gays than jews while in the 3rd R it was more jews than gays however the SAS leadership was known to be mostly gay so they were murdered by the young Nazi party.

The wierd use of mysticism and religion by the 3rd R is well known and shows an attempt to create a new religion.
In the US the Republican base relies on the Evangelicals which is a new religion with its farthest roots going back to England 100 years ago. The mysticism of the Bush administration is a secret affair. It is not the skull and bones conspiracy which we have all heard about. The Yale group is just training for young ruling class initiates to welcome the blood letting that they will be called upon to do. No the real Bush mysticism is based in bible codes created by Jewish experts who created a matrix of Saddam war and victory out of 11 by 11 characters arranged from the old testament. This is something they can never own up to in the real world.

The total police state US domestic spying program is way beyond anything the 3rd R could have dreamed.
