Breivik is an interesting topic
I'm Norwegian. It was 15 years ago, I was not racist at the time, and I never dove into the details, but there are some points you may not be aware of;
He bombed the government offices in the middle of summer, when he would have known that most workers (especially anyone important) would not be present.
His plan at Utøya was to kill former prime minister Gro Harlem Brundtland, who was scheduled to speak at the AUF summer camp. I believe he also only went there because he initially fled towards Sweden, before he realised no one was actually chasing him, and he took the opportunity to execute another (planned) attack.
Like I said I never dove in, but there are parts of his plan that were smart and meticulously executed (police uniform), and other parts that were, from the outside and of course with hindsight, not as smart or well executed (timing of the initial attack). The
results of his attacks are that the so called worker's party (Arbeiderpartiet, AP) surged in popularity, people rallied around the poor browns, the progress party (Fremskrittspartiet, FRP) that he was briefly a member of are to this day still maligned, and his name is
always brought up to silence discussion about the danger of islam (because he is White and not muslim). AP still sometimes use the "we were targeted by a terrorist attack" line for sympathy.
Things are shifting, and currently FRP is likely to get the PM next election, but I think that's
in spite of Breivik. In my opinion as a retard, the ways to use terror to
actually further your goals is either by repeated, unrelenting, and overwhelming attacks of opportunity (muslim terror), surgical attacks on high-level targets (kidnapping Maduro*), or by some extremely meticulous false flag - but if it is exposed or even suspected as a false flag, you may have hurt your own side irreparably, and even
IF you could successfully commit a false flag attack, you would still have to rely on the media to not lie about it. In short I think terrorism is a terrible strategy to gain political support.
*I'm not saying kidnapping Maduro was terror but I can't think of any better examples of this strategy.
