Were more nuke scenes left on the cutting room floor due to 9/11?

There was only ever one detonation.

They did make changes due to 9/11
Hollywood liberals didn't want to offend the animals that just attacked us on 9/11
so they altered who the enemy was from Muslim Jihadi terrorists to German Neo-Nazis.
In the Book they were Palestinian terrorists.

"CGSailor" is completely wrong...

"They did make changes due to 9/11

FALSE. The film was completed THREE MONTHS before 9/11. When scripting the film, the filmmakers decide the change from Arab terrorists to Neo-nazis because they felt Arab terrorists were cliché and having them pull off the attack would be unrealistic (which proved tragically ironic). Concurrently, there was a growing fear of neo-nazism in Europe at the time, with fascist parties gaining a lot of power in numerous countries, including Austria, Holland, Spain, France, Italy,...

As for your initial question, roximunro, it's called "style". Showing "a shot of the stadium disappearing into a blinding ball of light or something, or a mushroom cloud in the middle of downtown or something" would have been the obvious choice and no doubt a lesser director would have done just that. But what Robinson did was, IMO, incredible and just much more effective. Sudden, unexpected, destructive and done in an instant. Conveying the destruction and the horror of the siutation very simply and tastefully, without overdoing it. One of the best sequences in the film and that's saying something.

Drop it like it's legal precedent!

I think the short answer is that they wanted to maintain the feel of a thriller, rather than turn the movie into a disaster flick. I personally feel it was a good choice not to dwell too much on the results of the nuclear blast. As one of the above posters notes, it was more likely a matter of directorial style.🐭

I was wondering about this too. It just finished playing on AMC and there was an aerial shot of the city shown briefly just before the blast. For some reason I thought that the explosion was shown from that angle just before they cut to the hospital scene where the windows are blown in. It's very possible that there was never a bomb explosion shot from the air and I'm completely crazy! However, I'd be interested to see if anyone else remembers something similar. Films are often edited before being shown on TV for various reasons (violence, language, time etc), perhaps Sum Of All Fears has a television version as well.

As far as an edit being done due to 9/11, I think that would be very possible. I've never thought about that before, but it would make sense.

It's very odd how they handle the nuke in the film. It goes off, pretty explosion, some random shots of debris and rubble and that's really the only sense you get of anything having happened at all. Millions of people just incinerated? You'd never guess.
