Canada will be beside the US when it starts the steamroller. Public and political opinion indicate that the US will be able to justify almost anything - at least as much as the US public is prepared to accept - to fix this and make sure it doesn't happen again. What I glean from the BBC seems to indicate that England and probably the rest of NATO feel the same way. We're coming along, and it won't be as peacekeepers this time.
What about the rest of the world? Anyone from Pakistan? China? India? Hong Kong? Israel? Anywhere? care to comment on general sentiment where they live?
