Why do we want to catch bin Laden? To see that he stands trial in a duly constituted court of law for his crimes against the United States and its people.
I do not like the idea of secret tribunals. Something similar to Neurenburg is what is needed. I do not want to see him executed, but held -should he be found guilty- incommunicado for the rest of his life; with no way to contact his followers and no news of their doings.
And yes, oil just may have been at the bottom of his desire to destroy the US. Consider the fact that Russian oil is now available to the West. Kinda breaks the OPEC monopoly.
In bin Ladens mind this would be the final insult to the Arab nations, the destruction of the last bit of power the Arabs have over the West. Add to that the Caspian fields and the Arab nations are relegated to the backwaters of power once again.
Think about it.
