Raffaello Pantucci (RUSI) as a short overview, with a UK focus in an insurance publication. He starts with:
Amongst the reams of academic literature written on the topic, there is no single explanation or answer to how or why radicalisation happens. This process of radicalisation is a highly individualised one, driven by personal choices framed against a broader ideological backdrop.
He ends with:
The problem of radicalisation appears a perennial one, but how it expresses itself through different ideologies appears to broadly follow trends that go in similar directions; but as we move into a world where traditional groups hold an ever-more diffuse appeal and micro-ideologies start to emerge, how the threat picture expresses itself and who we need to pay attention to will become ever more confusing.
