The 2% is a political figure, conjured-up to make some (poorly) defined NATO spending statement. What if, we needed 10% to survive? Or 50%?
The things that matter are, that the defence spending is sufficient to provide the reliable defence of the nation. Therefore, the definition of the level of spending depends on the need. That is what the Gov should be doing, not fudging the spending, define the need, you Pollies!
