The threat is DOWN?

What is this man saying? That the threat of terrorism has lowered in recent years? The number of fatalaties from terrorist attacks is going down? Writing in The Spectator, Paul Robinson urges calm and suggests that our leaders are fear-mongering themselves into massive debt. Robinson perfectly articulates the irrational logic currently employed by Western leaders in their "fight against terror":

"We didn’t invade Iraq because we knew it had weapons of mass destruction and links with terrorists, but because we didn’t know that it didn’t, and ‘what if...?’ And we are clamping control orders on those now released from Belmarsh [UK prison] not because we know that they are terrorists (if we had enough evidence to know, we’d be able to arrest them properly) but because we don’t know that they aren’t and, again, ‘what if...?’"
