As Rodney Hide points out, Labour's promise to spend $3billion extra on defence over ten years is just empty nonsense. It's apparent they do see such a promise as being something the electorate will like - which is a good thing - but they figure the electorate and the press gallery can't count, which is bad - and sadly true.
The truth is that the Air Force will still need to run a cake stall just to keep its Orions in the air, and shouldn't even think about having enough to get its strike force back.
Basically, Labour's promises are the typically empty blatherings of politicians lapped up by headline-writing journalists short of a critical faculty. And the country still only has an National Anthem to defend us.
Personally, I believe that this country is worth defending, and that doing so is a legitimate task of government. Oddly enough, so do the Libertarianz, and they're quite specific as to what is needed - more specific even than is our present Government. Other opposition parties do at least realise something must be done: Check out what they're promising - National, ACT, and Winston First. Note that conscription has thankfully disappeared from Winston's policy proposal - expect it to reappear however if his poll rise reverses.
