It's time that we grew up as a nation when it comes to diplomatic courtesy. It's time the Greens revoked their "unofficial ban" on visiting political leaders addressing the New Zealand Parliament.
Some of the world's most powerful leaders like Germany's Angela Merkel and China's Xi Jinping are headed our way later this month after they've been to the G20 Summit in Brisbane.
Having political leaders of such calibre addressing our Parliament while it is sitting is not going to subvert our democracy. But the Greens' overblown and juvenile stance that only New Zealand politicians should be allowed to address a sitting session makes us look absurdly pretentious in comparison to our transtasman neighbour.
Yes, it’s disrespectful to other nations: yes, it’s juvenile, but surely nobody expects anything more from the ‘it’s all about the kids’ party.
But the only occasion (to date) in which a foreign leader -- Australia's former PM Julia Gillard -- has addressed our Parliament it had to be outside formal sitting hours.
This was because Greens co-leader Russel Norman -- an Australian himself -- reckoned having a foreign leader in the House could undermine the democratic sovereignty of Parliament.
It's tempting to observe that Parliament does a good job of undermining itself from time to time with bouts of raucous behaviour.
But the Greens' rationale for blocking Gillard was that while they had nothing personal against her, they didn't want to set a precedent for "unpleasant people" like George Bush.
Nothing is achieved by not listening to what others have to say and nothing illustrates better why the Greens are unfit to govern. International alliances are shifting sands. It takes diplomacy and maturity to navigate a way through those terrains not putting heads in the sand so other points of view can’t be heard.
