No offense to haloboy, but his comment is a prime indicator of how Canadians - despite how smug we are about better geography/history education than that generally presented in the US - need a considerably better history curriculum when it comes to the twentieth century. Unfortunately, when I was in high school (which was now some time ago, I grant, but post-1990) the 20th century was only really discussed in grades 11 and 12, and History 12 was an elective. The treatment of the 20th century in the 11th grade was shoddy at best for the period post-1945. Canada is just as guilty as other countries of focusing its Social Studies (or whatever its now called) on itself without fair treatment to global issues.
While the US bore the full brunt of McCarthyism and associated idiocy, fear of the USSR was pretty universal among NATO nations.
I graduated highschool in 2011, so perhaps it's been updated, and I can only speak of the Alberta curriculum, but we covered the Cold War in great depth. Spent almost the entire grade 12 year on it. Furthermore, you don't graduate without taking Social Studies 30 (Our equivalent of History 12).
The history aspects of grade 11 and 12 curriculum, (Focusing on nationalism and liberalism respectively) give a fairly complete historical picture of Europe, the USSR, and North America from the French Revolution to today and the economic aspects (The development of capitalism, socialism, and communism as economic theories) does the same from the Industrial Revolution forward.
Edit -
In fact the 'Canadian Content' requirements foisted on us by busy bodies in Edmonton and Ottawa were so obviously footnotes and shoehorned in that neither the teacher nor the students paid them much attention. Obviously I have a bit more detailed knowledge of Canada/US planning in the Cold War, versus UK/US planning, but in the big picture we barely mentioned Canada.
