Hmmm...I think it's probably too soon for most people to laugh at it, as it's still kind of inappropriate. In 50-100 years, though, I bet you'd get a lot more people laughing (laughing uneasily - they won't admit it's very funny, but they'll still laugh 😉 )
And as for the post about Al Qaeda vs Nazi vs etc.... yeah, militarily, they are probably nothing compared to our enemies of the past. But at the same time - there's something to be said for suicidal religious zealots. They may not have the firepower like the Japanese did to decimate our armed forces, but they can cause massive unrest by attacking civilians (as we obviously saw on 9/11), and it's hard for our country to quell unrest without restricting the freedoms this country is built upon (which we are seeing today - many conflicts regarding civil liberties).
