We have watched from the sidelines as a "war on terror" - sometimes bogus; sometimes genuine - has been waged thousands of kilometres away from the safe haven that is New Zealand.
This "war" - nebulous, imprecise, apparently all-embracing - has been an excuse for mass surveillance of innocent citizens; torture; and land grabs, and also as a useful vote-winning slogan.
It is not a war being won by the United States and its allies - the growth of the Islamic State movement in Iraq and Syria proves that.
Now John Key is taking New Zealand into the war with the prospect of troops being deployed in Iraq, most likely in a training capacity.
In doing so, he has immediately increased the risk of an attack on Kiwi soil or on Kiwis overseas.
