You've got to be kiddin Machjo. You cannot find a government more disdainful of nationalism, in terms of economic sovereignty and cultural integrity than that of Stephen Harper.. unless it was that of Jean Chretien or Brian Mulroney. These three sorcerers of the POST national ethos.. beholden to supranational institutions like the IMF, World Bank, WTO.. grovelling before the Global Investment Organism are ALL we have had for the last quarter century. Weaklings all, pygmies, quislings before the juggernaut of international trade and finance.
You're partially right. But in Canada neither side is truly internationalist. Bearing in mind that I am generalizxing here, I'll say that in general the right in Canada is pro-free trade (which I agree with), but then consider that Harper wanted to go to war in Iraq in spite of UN opposition. Consider too that in general conservatives are more anti-immigration and less inclined to recognise Canada's cosmopolitanism by respecting our First Treaties and and more decentralisation to allow for more regional autonomy.
The left isn't bad in general when it comes to respecting international law in international relations and immigration policy, but then tends to be more anti-free-trade. As for respect for our First Treaties and decentralization, there seems to be more division on that front.
To be fair Harper has made some moves towards recognizing Quebec as a nation and recognizing our First Peoples, just as the NDp has made some efforts to recognize Quebec autonomy with regards to the language issue for example.
They both have their pros and cons, but for the most part where the left is more cosmopolitan, the right is more nationalist, and vice versa.
Perhaps I ought to clarify that I have a much wider interpretation of internationalism. I do not limit it to the economic level, but also military, political, diplomatic, interpersonal, cultural, and between cultural groups even within a nation's boundaries.
For instance, I'd consider the Official Languages Act to be somewhat nationalistic in the sense that it tries to impose an asymmetrical relationship between Canadians of European descent and our First Peoples.
