Hat tip to WoTR for this article 'Lone actors -v- remote controlled jihadi terrorism rethinking the threat to the West' by Professor Mullins, an Australian and currently in Germany. The purpose is well explained in this sentence:
It is therefore important to re-examine the concept of lone-actor terrorism and to try and appreciate where it fits within the overall spectrum of jihadist terrorist activity in the West.

This graphic is very useful, especially when the author points out that the numbers in brackets refer to number of fatalities vs number of attacks.


He ends with:
The threat to the West is real and we cannot afford to let down our guard, but our adversaries’ intent is far greater than their capabilities. Moreover, this is an indicator of largely successful counter-terrorism. Members of the general public and policymakers alike should understand and appreciate this.
