Since there are excellent analysis of it available elsewhere, and because it's not directly linked with the military of Iran, I'll attempt to keep my comments on the issue short.
It's clear that this will have far reaching consequences which will forever change the nature of international terrorism.
What I wish to make note of however is the fact that Bin Laden was not captured by a multi-pronged military offensive charging through the hills of Afghanistan with tanks and waves of helicopters. The operation was fundamentally an intelligence campaign.
The solution (or as close to one as we can obtain) when faced with threats like Al Qaeda is not a military one in the sense that we could invade a country like Iraq and Afghanistan and "beat it out them". In fact, that's Al Qaeda's strategy - draw the US into long bloody wars that drain our national morale.
The death of Osama Bin Laden should serve as a wakeup call to the US to reinvest in a full spectrum of tools including the ones that aren't glamorous or expensive as stealth fighters or a new generation of super-carriers. Intelligence is what got us Bin Laden, and intelligence is what will win us future wars.
