I wonder what history if any the PNAC folks read to come to that conclusion. Which countries, religions, movements completely knuckled under to invasion from abroad? The PNAC folks failed for the same reason the Bolsheviks failed. The theory sounds nice, but it runs completely contrary to human nature. Humans chafe at attempts to control them. Heck, the community my first wife grew up in had a school principal fired because they thought he was bringing in "Big City" ideas from Long Island to Upstate NY. People do not like being told what to do or how to live by perceived outsiders. Religion and religious fervor not only do not die under attempts at suppression, they THRIVE in such environments. If that were not so, Christianity would have died early on in the Roman Empire. If PNAC had only performed adequate research regarding invasions or occupations of the Middle East, and invasions of other countries and regions throughout history, they could have avoided their erroneous conclusions.
We see in the Middle East the consequences of this error in understanding fundamental parts of human nature. Our invasion of Iraq and toppling of Hussein has had the opposite of PNACs's intended effect. The Middle East is erupting like a super-Volcano. Iraq is in the throes of a civil war, Hezbollah is in the process of taking control of Lebanon and along with Al-Qaeda and Hamas and other radical groups are taking in recruits at a faster rate and in far greater numbers than before our ill advised Iraq venture. The rest of the world sees us as the global bully and people hate bullies.
One would think that this terrible result would chasten PNAC and cause them to rethink their militaristic strategy. Such thoughts would be incorrect. As these two of many articles on the subject by PNAC members make clear: http://www.weeklystandard.com/content/public/articles/000/000/006/585tdlqf.asp and http://www.washingtonpost.com/wp-dyn/content/article/2006/01/17/ar2006011700893.html they still think the best course of action to solve US problems in the Middle East is military action and Republican foreign policy is dominated by PNAC driven neocon thought.
