Europe's biggest problem is its success.

Starting from the ruins of the Second World War, we - all Europeans said, after centuries of fighting each other, we're going to build permanent arrangements in which peace between European countries is secured, freedom is secured, and growing prosperity. And that's what we have done over the last 70 years.

A central claim of the Bush administration's foreign policy is that the spread of democracy in the Middle East is the cure for terrorism.

Nuclear proliferation - the proliferation of WMDs altogether - is one of the greatest dangers of our time.

Every step that produces a single job for a currently unemployed European should be taken. Every centimetre of red tape that puts someone out of work must be torn up.

America is divided by a great argument about itself. Europe is divided by a great argument about America.

I have also been saddened, though hardly surprised, by the weakness of the EU's reaction to the criminal attack on the Danish embassy in Syria, which seems to have been permitted, if not actively encouraged, by the Syrian regime.

So what were Europeans telling their leaders? The general message was perfectly summed up by the cartoonist Chappatte, who drew a group of protesters holding up a placard shouting Unhappy - and one of their number shouting through a megaphone into the ballot box. There are 28 member states and 28 varieties of Unhappy.

The Eurozone has clearly gone spectacularly wrong, pulling down all the continental economies.

If you had said to anyone in 1945, at the end of the Second World War with the continent it ruins, that you could have a European Union of 28 member states stretching from Portugal in the West to Estonia in the East, all of them more-or-less liberal democracies - they wouldn't have believed you.

America should do a reverse Columbus. The world no longer needs to discover America but America urgently needs to discover the world's view of America.

Yet another thing Canadians and Europeans have in common is an obsession with the United States, and with distinguishing themselves from it, often by crude stereotyping.

One thing, however, I know with certainty: violence, or the direct threat of violence, of the kind we have seen in the past few days, is totally unjustified as a response to any published word or image.

Canadians tend to be a bit more religious than most Europeans - though not more than the Poles or Ukrainians. Most important, their attitude to immigration and ethnic minorities is more positive than that of most Europeans.

Europe is a woman, now middle-aged, who has already had a number of heart attacks and is currently experiencing the biggest health crisis of her life, but one that need not be fatal.

Well, that's the way democracy works. We have to build this Europe with the material we have at our disposal. And this material is national democracy.

That said, the question remains: how to strike the balance between free speech and mutual respect in this mixed-up world, both blessed and cursed with instant communication? We should not fight fire with fire, threats with threats.
