Jaidi, Iran can play ball with the rest of the world because they have oil. Until recently, when boiling points were reached, 'political Islamists' like MB in North Africa were not even allowed to seriously try for office. Groups like Shabaab see only two routes - to routinely get denied power & legitimacy by more powerful forces, like what happened to the UIC before them or MB for decades or Hamas in Gaza today-----or they take the other route and play a different set of rules altogether, which is to take the Taliban route and just open a war without end....eventually you either win or lose through attrition, as opposed to being a lone-wolf and trying to play a game that you're supposed to lose 100% of the time. The Shabaab actually have a better chance with their current lunatic strategy rather than playing it safe in a rigged sport.
I was mainly addressing Udun's point that AlShabaabs strategy can be viable in the long term. It clearly is not. There is no long term hope for people who operate purely on ideology, regardless of what it is in the long term. Replicating the Taliban script surely is not a template for success is it? Even the Taliban survives because of major regional interest in the region. The Afghan Taliban still gets major support from the Pakistani ISI. Who does alShabaab have?
The other groups have evolved and adjusted, and begun to show pragmatism based on their circumstances. They've learnt from their 90s experiences. Can you say the same for alShabaab? If they showed an iota of pragmatism and political insight they could've easily gained power at their peak. Their example relates much more to AQ than it does anyone else IMO. They've thrived off Somalia's power vacuum and chaos to fare a bit better, than the likes of AQ in Yemen and Iraq, but when it comes to strategy, and their outlooks on the world that is who they are the closest to. At least on the leadership level.
