Mark Steyn, interviewed on Enter Stage Right, illustrates Canadian anti-Americanism:

The other day The Ottawa Citizen had a letter from a Vancouver lady objecting to any Canadian participation in continental missile defence on the grounds that an intercepted nuke could wind up scattering contaminated debris over the Canadian countryside. The logic of her position is that she'd rather that nuke continued on its way over the border and took out Dallas or St Louis. Say what you like, but that 's consistent.

And Natalie Solent fights UK anti-Americanism, pointing out that the British Margaret Drabble's hatred of airplanes painted with vicious faces doesn't justify the feelings it aroused given the RAF has also followed that practice.
