Brave only when there is disaster?

So I watched "World Trade Center" last nite and I have to say that I was pretty impressed. It made the experience horrific on both a public and personal level. The sight of wounded men being helped out in stretchers by hundreds of people was both heartbreaking and heartwarming at the same time.
It did make me question one thing though. Why does something on the scale of the World Trade Center being attacked have to happen in order to bring people together? Yes, this incident showed that there is still good people in this world who are capable of helping simply because they are needed and it is the right thing to do. Well, they are still needed. There are a multitude of problems around the world that desperately need the help of good people, so why are they being ignored?! Apparently we need to hit these people in the face in order for them to step up to the plate. And that is sad.

On a side note: The movie was almost killed for me when a marine says the line: "They are going to need good men out there to avenge this" *sigh* Yes, lets go and do the same thing that they did to us, but to a greater scale. That will fix things!! *shakes head with disgust*
