That's one of the reasons it is such an important decision. One that should probably require more support than it has had.
A parliamentary vote would likely have been deadlocked 60-60 without Mike Sabin's vote. No vote was held. Opposition MPs and government support partners have criticised the deployment. Mr Key said angrily in response: "This is the time to stand up and be counted. Get some guts and join the right side." Who's he calling "chicken"? As I have said before, this topic needs a level of debate well above the school playground level.
Even constant references to the disgusting murder and torture porn images disseminated by Isis do not sit well. "I will not as leader of New Zealand stand back and see Jordanian pilots burned to death," he has said, and repeated.
As terrible as it is, it is emotional blackmail to use this Isis propaganda as an excuse to go to war. Do not forget they are the ones committing the heinous acts and providing the images.
For whatever reason, the actions of Isis are designed to provoke a response. We should not have been provoked.
Any action by New Zealand should be measured, well thought-out and debated, and the right thing to do.
Now that we have committed to Iraq, it is fair to say not all those criteria have been met.
