Why Target the Super Bowl?
One thing that always bothered me about the book/film is that the terrorists targeted the Super Bowl in an attempt to trigger a nuclear war between the US and Russia (still the Soviet Union in the novel).
Why target the Super Bowl? I remember the scene in the book when the Native American who is helping them takes them to the game at the stadium during the season, but still, it made no sense as an attempt to trigger WWIII.
Why target Baltimore (or Denver in the book). Wouldn't having the plot of a bomb over NY or DC had been more likely to spark the war? Think about it, had it been DC, much of the leadership, perhaps even POTUS would've been gone. Whoever was left would've been certain it was Russia when coupled with the tanks in Berlin and the Akula attacking the US Ohio class sub in the Pacific.
That's a plot hole that Clancy left that I just never understood. He couldn't have been saying he didn't want to remove the entire US senior leadership from the world he created in the novels as he ended up doing just that in the following novel when the Japanese 747 crashes into the joint session of Congress.
