Jordan Garretson (One Day in September)

One Day in September was interesting because it showed the different implications Nationalism can have for a country, particularly on a stage like the Olympics when feelings of Nationalism are near all-time high levels. For the Palestinians, they were viewed the games as an opportunity to show off their power. For them, it was the ultimate chance to flex their military muscle and make sure everyone across the globe knew about it.
These Olympics were very emotional for the Israelis coming in, knowing that the Holocaust had taken place just over 20 years ago, in the very same country as the Olympics. For them, it was a chance to show their resilience.
The Germans were ashamed of what transpired in WWII and were trying to reconstruct their image across the world.
Ironically perhaps the most successful of the three were the Palestinians. Although it likely only caused others to resent them, the Palestinians proved their military potential and the fact that they would resort to any means necessary to demonstrate it.
What was supposed to be a time of coping and overcoming the past for the Israelis/Jews instead become a sad reminder of their past.
Finally, Germany was just embarrassed by what transpired and their security failure. Ultimately, Nationalism was at the root of all country's motives. Unfortunately it resulted in a violent conflict, possibly one of the most extreme cases of Nationalistic pride.

I think the comments by the Palestinian terrorist at the end of the documentary show just how strong Nationalism can be for some people. It's disgusting and mind-boggling that he has absolutely no regret for what he did, but it shows just how important their act was to the Palestinians.
