Why do you think trying to reduce the threat of terror attacks is of a lesser priority than the attacks you mention?
Because the nationalist agenda it promotes ahem, appeals to the average intelligence and reasoning skills of the electorate. A bit like the moustachioed German Chancellor in the 30s. He is using directed anger generated from the start of the automation revolution (with associated widescale job losses in steel, coal and the like) to get himself votes based upon all of those illegals coming across and taking our jobs.
