I think it's a bit far-fetched to to do any analysis whatsoever of his political views, he's just a nutjob.
Having read more of his manifesto I'm increasingly inclined to agree. It's not that his writing is deranged like that of Jared Loughner. But there is still something mentally "not quite right" about it. For instance, when discussing which platform he should choose Breivik rejects "hateful" ideologies and "controversial views" because these do not have "mass appeal". He then admits that he himself is part of a "relatively cynical/cruel/goal oriented armed resistance group" but believes nonetheless that this group is supported by 50-60% of Europeans "due to the fact that we oppose ALL hate ideologies and we consider it illogical to fight hate with hate." But he then immediately adds that "this does not mean that we will use less brutal methods in our operations."
He seems to think something along the lines of "we will win support by having nice beliefs whilst carrying out cynical/cruel acts of violence".
Here is how he explains why he did not join a national or ethnocentric group:
I understand that many nationalists only care for their own nation and culture. However, all Western Europeans are in the same situation ... Pooling resources and especially knowledge is essential. Obviously, this cannot be achieved if you require that your potential members follow un-appealing principles and codes such as that of the national anarchists (at least many of them). A hateful ideology (white supremacist), death metal, Odinism, conspiracy theories does NOT have mass appeal. Some of the local nationalist factions have very controversial views and lifestyles that do not appeal to a broad specter of people. ...so called national anarchists will never be potent enough unless they pool their knowledge base with pan-European organisations. Mass appeal should be the most essential factor in this strategy. Obviously, the PCCTS, Knights Templar does not have mass appeal as we are a relatively cynical/cruel/goal oriented armed resistance group. However, our primary foundational principles (a majority of them) still have mass appeal and are supported by as many as 50-60% of all Europeans. The reason for this is due to the fact that we oppose ALL hate ideologies and we consider it illogical to fight hate with hate. Of course, this does not mean that we will use less brutal methods in our operations.
He also explains in this part of the manifesto why he chose to go with Christianity. It was for pragmatic political reasons rather than from any theological commitment. He thought that the Odinism (paganism) of some Norwegian rightists would alienate central and southern Europeans:
Q: Why did you choose an allegiance to a group with Christian values and pan-European goals instead of a purely national/regional group?
A: Many have asked this question. My choice has nothing to do with the fact that I am not proud of my own traditions and heritage. My choice was based purely pragmatism. All Europeans are in this boat together so we must choose a more moderate platform that can appeal to a great number of Europeans – preferably up to 50% (realistically up to 35%). Choosing a local/national group would be counterproductive as all the groups I am familiar with are Odinist orientated and not Christian identity groups. It is essential that we choose a banner that has the potential to appeal towards central and southern Europeans as well.
It's odd that he should answer "Many have asked this question." Who could possibly have asked him this given he kept his project a secret fromt he world? But note again that he chose Christianity, on pragmatic grounds, as a "banner" rather than as a religion.
A few other observations. According to his manifesto Breivik rejected ordinary political work for change as early as the year 2000 when he was about 21 and that he met up with the "justiciar knights" group when he was 23. If true, that means that his political course was set many years before he could have come into contact with writers like Fjordman.
He also claims that this "justiciar" group was aiming to achieve its goals in the year 2083. That's odd too. If it's such a long term, multi-generational strategy, then why not take the time instead to build up a political movement? Why go off on a sudden rampage?
