If a significant number of countries were to opt out of democratic and representative government in favour of government by despots, dictators and demagogues, the whole balance on which world peace and stability depend would be disturbed.
Fortunately for us here in New Zealand, such fears and concerns seem remote. We might or might not like and support our current Government, but we have no reason to fear for our democracy. We can be sure that, if we so decide, we could change the Government in a properly democratic election and that the newly elected Parliament would be properly responsive to our wishes.
But any complacency about the unchallengeable democratic basis of our system of government should not, perhaps, survive the contemplation of what is currently happening in another and similar country - one with an unequalled history of democratic experience.
In the United Kingdom, a democratically elected Parliament has quite deliberately and repeatedly refused to endorse and give effect to a decision taken by the British people in a referendum authorised by that same Parliament.
The procedural machinations to which the various factions on the Brexit issue have given rise to accusations from some quarters of undemocratic sharp practice.
It is no doubt true that, in any struggle between Parliament and Government, most democrats would instinctively side with the elected representatives. But, in respect of the difficulty encountered by the British Government in giving effect to the Brexit decision, that does not seem to be so obvious.
While it is true that the British Government has itself tried at times to by-pass constitutional principles in trying to implement the Brexit decision, it is those who are using Parliament to reverse that decision who are responsible for the greatest breach of democratic principle.
The basic fact is a simple one. More than three years after the referendum decision, a Parliament stacked full of MPs elected on a promise to "respect the result" of the referendum has contrived to frustrate any attempt to give effect to the people's decision.
These MPs have taken it upon themselves to "correct", as they see it, a mistake made by the people. They have set themselves up as a counterweight to that democratic decision on the self-proclaimed ground that "they know best" - the classic claim by anti-democrats through the ages.
They seem not to understand the risk they are taking. If the British people once conclude that their elected representatives no longer recognise any duty actually to represent them, there is then the real danger that they will lose faith in the whole concept of representative democracy.
They might then conclude, like those elsewhere, that they have no other option than to take to the streets. History tells us that democracy is a fragile flower; if is not constantly nurtured, it will die.
